the coral tpu does what it does and it's not bad at it. The documentation is good , and quite a few people use them practically. They're available readily.
What's upsetting about the state? Continued development?
however, to your point : being google affiliated is a huge red-flag for longevity.
They were completely sold out for 2-3 years (2020 onwards), and Google wiped documentation (https://coral.ai/products/accelerator/ redirects to the main page, which has no reference to the original Coral). I can't tell where there's an official place to buy this. I see some on Amazon, but that might be resold.
