You are not "simply using" an internet browser. You are using an entire (browser) OS in itself on a 4x pixel count display with antialiased text, transparency, blur, scaling, video compositing... The OS itself is using additional compositing for windows using indirect rendering - all the things that add latency. Additionally, you are using a remote application that has it's own latency when talking to the remote server and even locally executing JS is doing everything in a single thread, plus V8 JIT only works for hotspots in the code.
Do any of those additional things add value to the user in this application?
If your taxi driver takes you for a 2 hour scenic tour of the city when you simply wanted a direct 20 minute trip, you don't cut them slack for all the extra work they did, you complain they provided a terrible service.
