In my opinion. The majority of computer/phone users is not very technical. They get used to how something they use works. It keeps working as is for a long time.

Then when small changes make it worse, they just accept them. Its just a bit worse. No biggie, then at some point they are used to the new normal. Something else gets worse and the whole thing repeats. It has to be literally unusable before such users switch to a new thing. Like reddits servers need to shut down, that kind of unusable.

95% of users are like that (1).
