I will add, that enshittification is a big part of the process. Money drives companies do things users do not like, and the only power we hold against that, is to walk away. If we do not use that power, things will only get worse, or end up in a monopoly situation, where you lose most of that power, and all of it, if it is something, you must use.
What often happens is, that the wave kind of starts as a small movement away, and when the enshittification goes too far (and competition has not been killed successfully yet), it gets bigger and bigger. And that wave brings money, which either starts or hastens the enshittification process of the product people moved to. And the cycle repeats.
