It's an interesting point, I'm a software/network automation engineer with absolutely no legal training - but a lot of experience in working for some of the big US tech companies and I learnt one big thing from that experience. These companies value customer experience over absolutely everything else imaginable, that might not mean much to you, but they absolutely
obsess over customers and giving the customer what they want.
How is that relevant? When it comes to the social media companies I think it becomes very relevant. As you probably know - social media companies primarily make their money from selling your data to advertising companies, who in turn make money from customers buying their stuff, so you have the users of the platform, then the customers of it; the advertising companies.
The customers are essentially controlling the whole show, if they see their advertisements mixing alongside users posting things which they find "unpalatable" depending on the current societal fads; because they're the paying customer - they hold a lot of sway in dictating what's allows vs what's not allowed on the platform. Because the social media platform is a private system owned by a private company, they construct their own terms and conditions, ergo; they can allow or censor just about anything they like, within the confines of law of the country in which it's operating. (obviously these laws differ drastically from country to country)
The thing I struggle with a little, is that these social media companies have such an enormous critical mass of users (billions) that the rules of who sees what, are essentially being dictated by advertising companies, not the traditional institutions like courts or governments and those rules are driven by one main metric; money. I personally don't think it's very healthy for society to have an industry deciding these things, based purely on it's own business interests, or in the case of cancerous garbage like TikTok - what a foreign government wants you to see. (that's a different topic entirely)
In the final analysis, when awful Alex Jones has to pay out $$$$$$$$ to the families of Sandy Hook - I'll be playing the world's smallest violin, and as somebody who doesn't use social media at all - none of this affects me. I guess I just feel a hint of trepidation when I see kids swarming around these platforms,
and they're being re-educated on what's good/bad by frankly - whoever has the most cash..
