I guess the eventual culprit is capitalism, where profit is the ultimate goal for everything, so there will never be a single product that is not enshittified in this way.
The best part? If you don't like it, there's nothing you can do! It's the whole culture.
The thing is, they will have to switch to maximizing monetization (or die trying). Those investors are ultimately in control, and while they are happy to gain market share for now, that's what they will demand in the future.
They will keep a free version for as long as it's working for them, but you will be monetized, one way or another, sooner or later, and you might not enjoy it.
The AI is a symptom of the problem. If it weren't AI, it would be something else.
I honestly think this is for the better, (un)supervised learning models and other machine learning models with a reasonable number of parameters (k-means clustering, Markov Chains etc.) are usually not called AI any more (and honestly haven’t been for some time; machine learning has been much more popular for at least 10-15 years in my experience).
