To your first point, absolutely! Your online behavioral data is what you give in exchange for use of the platform. That's the contractual agreement users make with service/platform. We also have the right to re-negotiate those terms, or just leave the platform. It's a somewhat different matter with ISPs and OSs. We could move to Linux or switch ISPs, but there are monopolies of providers - if we're lucky, we have 2 ISPs serving our region - and the OS options are limited too.

Here's a situation to be aware of: I run Win10. The apps it installs automatically have rights to continuously run in the background, use our cams and mics, access our pics, our account info, our contacts, docs...That's just Edge, the browser. I disabled a number of apps a few weeks ago after finding that Skype had - all on its own, transmitted 6.3 MB of data over my network over a period of 3 hours and 42 minutes within the month of August alone. I NEVER use Skype.

To your second point, bloggers, whose posts receive unlawful or offensive comments are also not liable for those comments. The way the law code is written, users have the right to decide to delete or hide comments. The way it actually works, the platforms are overriding bloggers' rights to manage comment content visibility.

Over the past couple of years, Google has been shadow banning, using spam flagging. YT channel hosts weren't aware of it, but a simple count of comments, compared to the total shown at the top of the comment section, revealed it. In any situation that I found, the comments weren't criminal or offensive. On my own comments, logged in, I would see them. Logged out, they'd be hidden. The way we're discussing now, is the way I usually write, so...?
