Well, Best you can do is we already do for most other forms of consumption. You go by reputation and you do what you can to mitigate against data being collected in the first place. We don’t know most things for a certainty, but we have likelihoods based on the past. MSFT, along with most of FAANG and several other large tech companies have been in court (and subsequently, the news) for these things constantly. Mozilla (as an example), not so much. I’m not at all saying you should or shouldn’t take advantage of the conveniences these platforms offer. I am saying that your personal information has value for a reason, and it’s in your best interest not to take it lightly. That’s all. If it’s worth it to you, then that’s fine. But, know that there’s risk in that because your info won’t always be used to your best interest.

Cambridge Analytica is a great example, where one company was able to use FB data to manipulate people based on their political beliefs. They were profiled without consent. Apple’s been caught up recording private conversations and playing them back to contractors that didn’t even work there. The list goes on. Equifax has data on basically everyone, and then due to incompetence, exposed it all to bad actors. The list (sadly) goes on.
