>These huge social media websites need to be abandoned and be replaced with places where people can actually communicate and share information with each other without censorship or surveillance
While technically true, that's not realistic on a larger scale. How are you going to convince millions of people to migrate to another platform? Most people will just whine about how X site doesn't have Y feature, or that some of their "friends" won't be on there, or they'll refuse outright because people say Z thing that the media told them not to like. Most attempts have been blocked or subdued by backbone services like Cloudflare, and they get away with it because they're private companies and can do whatever they want, or whatever.
The real problem isn't competition, it's a lack of competition resulting from the lack of antitrust enforcement. If you looked into any subsector of technology or media, you'll find that it's completely dominated by a handful of companies (and when they cooperate, it's no different from a single company dominating everything). You'll have two to six companies at the very top, and they'll control almost everything else. These companies will lobby and collude with the government to ensure that they keep their lofty positions.
You're absolutely right, but let's not forget that diabetes wouldn't be nearly the problem it is now if not for all the crap that "food" companies are selling us. It used to be, long before any of us were born, that you could just buy normal food from the store, and that was the end of it. Now you have to actively look for anything truly healthy, and all that stuff's getting more and more expensive.
The same can be said for cancer. You wouldn't believe how much carcinogenic crap is piled into foods marked as "healthy" these days, and I'm not just talking about fast food. I'm sure you've been to the supermarket, and have seen multiple products (like "butter alternatives") that are filled with chemicals processed to death from plants. They say it's plant based, so it must be healthy! No. There are some plant oils that really are healthy (like olive oil, and pretty much everything else that's been around for over a 200 years), but most of it now is processed to death and back. To give you a more infamous example, just go ahead onto youtube and look up "how to make margarine". Pick any video, watch it all the way through, and tell me that you are honestly considering eating anything made with it ever again. Now realize that all the horrifying chemicals which go into that (and more) also go into most food products made today. Next, go to your actual local supermarket, into the bread isle, and count how many loafs have "bleached" or "(X plant you've never heard of) oil" in the list of ingredients. It's disgusting.
Don't even get me started on soy products. The fact that their most loyal consumers need fucking robot bottle openers should tell you enough.
>I've been dealing with an apocalyptic feeling of dread recently
You and everyone else with two braincells to rub together. The world is not moving in a good direction.
