Yeah sure, but it doesn't explain why. If I were to point out to anything, it would be monetization - starting from early ads ruining everything with pop-ups, through corporations gathering data, bad actors exploiting every little vulnerability to get some leverage, to users themselves aligning themselves with money; less and less people doing what they want just for fun, but rather adhering to corporate guidelines and ad strategies to get as much as they can out of this system. So much that other internet users who don't get anything out of it would also start behaving that way, maybe with hopes of getting a slice of the pie at some point. Maybe their next tweet will be a hit?

And in totality, it's not a bad thing - people that would probably have a boring job all their lives otherwise have built their wealth and connections, and the audience has been entertained. But money sucked the fun out of it.
