There was a time before people called websites "platforms". A time before gigantic websites full of thousands of other people's uploaded files, where the websites are used for surveillance and advertising delivery. The operators of these mega websites, posing as so-called "tech" companies, argue they are providing a valuable "service" to web users, valued at a price of zero dollars. Truly they are only interested in providing a service to advertisers. If advertisers stop paying, the operators will be forced to scale back the surveillance as it's too expensive to host peoples' files for free. If people are paying for their own hosting, like they pay for internet access, then third party websites cannot claim ownership to access logs for peoples' files and other metadata that is useful for advertising.
