I don't think Qualcomm bought them to destroy them. I think they see Arduino as a gateway. Instead of hoping students will learn ARM it's more reasonable to leverage Arduino's simple nature to act as an on-ramp for more low level developers. I wouldn't be surprised if Arduino IDE saw a revamp to better support jumping the gap between the Arduino to Snapdragon.
ST and TI do the same thing with their boards too and it's not a bad strategy.
The Raspberry Pi Pico blows the Arduino out of the water in terms of computational speed, available RAM and so on, and it costs a fraction. I don't remember using an Arduino since the Pi Pico came out. And if the Pico isn't enough there are the bigger family members waiting in the wings. For me Arduino is mostly over. And then there is Espressif as well, they make some neat boards.
Long live Teensy [1]!
I just wanted that someone mentioned these Arduino-likes in the comments. I suspect many of you have come across them though.
The teensy is so weird though. At least back when I played with them. They put a secondary chip which let's you flash over USB but they cover the debug pins and the only way to get serial over the USB port is to have a whole USB stack as part of your application. As a development board I would rather go with one of those STM32 backed boards and a knock off STLink, you need the STLink to flash, if you want DFU you can add that yourself, and you get a debug adapter.
Do you mean the Uno specifically? There are a lot of Arduino boards with varying capabilities.
You seem to equate gateway product = affordable but, IMHO, a gateway product is something that people who are not in the field are likely to stumble upon. I recently saw Arduino kits for kids at a small local bookstore, I can imagine someone thinking "hey this electronic thingy looks cool I'll buy one for my niece's birthday". On the flip side, people who don't know anything about microcontrollers are not going to look online for Chinese Arduino clones.

But high chance they will look it up on Amazon/Ebay/whatever e-store and buy a clone without knowing.
clone relies on hardware being designed and software written - this takes a lot of money, so you can't just count the final price of parts as the price.
Arduino is open sourced in hard and software which allows this cheap cloning to exist. It also helps a lot with software and docs, which makes it cheaper for them.

Hah! I like to underestimate scope as well, but this is really something else. Definitely a competent engineer could make something like this. But a couple of months maybe. You won't even read the documentation for the chip in a day.
I have been modifying Arduino libraries for weeks, there is much more work in them than just a single day. Granted replacing the Arduino IDE with Autoconf took 3 days. (2 and a half of which were spend on analyzing what the IDE does.)
It’s not quite that easy, and besides the hard part is the SW. arduino spent years writing SW code and still does to make it easy to run, debug issues and provide support.
Also a million dev kits is unrealistic for vast majority of companies 5-20k is more the number I hard.
Some years back when bluepills ran $2, Arduinos seemed to have no point. Today, you can buy an ESP32 dev board with wifi for $6. Or an Arduino Uno Wifi for $55.
Note that both Bluepill and ESP32 can be programmed in the Arduino IDE, using the Arduino library, and the vast library of Arduino sketches and 3rd party libraries (as long as they don't use AVR assembly language.
So can the Pi Pico, the Milk-V Duo (one 64 bit Linux core, one 64 bit microcontroller core), and many others.
While that is true, both Espressif and the Pico have their own SDKs, and they're really well written too.
The Arduino SDK is the simplest to use, sure, but the Pico framework (I don't have experience with the Espressif one) is extremely good, and the Pico's PIO is a godsend. I used it to implement 3 wire SPI (data bidirectional on the same wire) at almost 'real-time', which is to say, at half the speed of the hardware SPI controller (half the speed because the interface clock is put up one cycle and down the next; this also gives enough time for data shuffling).
Why does the Arduino SDK necessitate a huge markup on Arduino boards, when $0 of every computer I buy to run Linux on goes to GCC?

Generics may have the same active ingredient but (vastly) different pharmacokinetics - i.e. different absorption rates/retention in the body. For basic stuff such as painkillers that's one thing, but for more sensitive medication such as insulin, antidepressants or anything related to the cardiovascular system (heart rate, blood pressure and clotting) one has to be very careful when switching between brands.
Its relevant, however, that the Bluepill and ESP8266 cores for Arduino were originally independent reimplementations by third party hobbyists, not made by Arduino. And Espressif themselves have always developed the ESP32 Arduino library implementation. They weren't completely freeloading off Arduino's work, and Arduino (the company and the ecosystem) heavily benefit from contributors of all sorts. Particularly in the case of Arduino and Espressif, they have been successful together.

But you still used the Arduino SDK with the bluepill, so clearly Arduino had a point. Unless you were one of the few masochist who dealt with the STM32 toolchain directly for fun?
The Pi Pico is such a breath of fresh air in that regard. Finally a decent-enough toolchain for a decent-enough performing ARM MCU!
People are making so much of this when it seems so much simpler. Qualcomm likes buying high-margin businesses, and Arduino is a high-margin business. Gross margin on their boards is over 90% (hence why you can buy a Chinese clone of a $30 board for $3) and this trend shows no signs of slowing down. The TI equivalent of the $30 Arduino Uno is $5, and it's a true gateway product.
