I think there is more to it. For Internet company, user is what generates value. So it make since for those companies to grab their user as tight as possible especially when the competitors are doing the same. On the same note, if a user just don't want to login or use the app, then the user is no value or even a negative value for the company. For that, a company can intentionally annoy (the actual word used is Convince) those users until they give in. With all that been said, what I wanted to point out is, sometime, parasite can be successful. This is why we have many types of parasites in the real world. Automatically assuming "'parasites' will just die" is not going to help if the end goal is to kill all the parasites.
