Sure it could happen, but I don’t understand what relevance that has when you compare it to the fact that you KNOW without a shadow of a doubt corporations are going to sell your data to the maximal amount they can, even if it is illegal.

Besides this isn’t about our data being sold or not being sold really (our data will be mined and sold by somebody so long as it is publicly available on social networks), it is about who has the power and who doesn’t. Does a single corporation run by a billionaire fascist-baby have the power or an imperfect constellation of developers, instance maintainers and moderators?
