If that were true, it wouldn’t be the way it is.
Just because it causes your disengagement, doesn’t mean it causes disengagement with the vast majority of their userbase.
They’re also more concerned with ad views and clicks, so if you’re not the kind of person who gives a crap about ads… they don’t really care that much about you.
They don’t have to be 100% competent, but they are very competent at what they want to do… which is monetize the technologies and services they provide. They’re not trying to make something that people can use well and enjoy… they’re making things to make a shit-ton of money. The two goals are not generally mutually inclusive.
Yours, on the other hand, is predicated on the belief that they’re all super-incompetent and have no capability of doing anything right ever… which is confusing considering they’re a multi-billion dollar company and not just some guy in a shack banging rocks together to see how they sound.
