So my concern is: Do these social media corporations really think of the users or mostly about their own value?
Will be nice to know your opinion.
They care for their users because we are their products to the advertisers. But what kind of care is that? they mostly care somehow in a way to provide good service and add more features that we can enjoy.
But when it comes to anonymity and data, they don't care if you care for your own information. As long as you're on their platform, they have the authority to do what they want with it.
