It would seem that point 1 makes it even easier for companies to slurp everything about a person. Point 2 is only true if the data has no other use. Political parties might find a lot of value in discovering Mastodon users whose posting habits indicate that they are currently voting one way but are disatisfied with that party. Insurance companies might also be interested about users being part of groups for people with certain mental or genetic diseases. I can imagine a sort of "reverse glassdoor" site where employers can pay to get a complete profile of everything an applicant has ever done or said online. The CA business model works very seamlessly with ad targeting, but that is by far not the only use for such data.
