Media was once free and then collapse to be owned by ABC, NBC, CBS and a few dozen newspapers.
This was originally about network neutrality, but it applies to what we're seeing right now:
You can feel free to create your own too. Social media platforms existed before Twitter and Facebook, and eventually other platforms will succeed Twitter and Facebook.
Can it be expensive to start a company from scratch? Yes, it can. But that has always been the case.
But don't fool yourself into thinking my little instances have any sort of effect compared to the big mega-corps of Google/Facebook and Twitter.
As I said, there were social networks before Twitter, Facebook, and Parler, and there will be social networks afterwards.
starting a newspaper is significantly more costly and difficult than starting a social media app. You're confusing the fact that websites like Parler are so toxic that nobody wants to do business with them with the inability of actually starting it, which anyone with a laptop can do on a weekend.
