There’s no design authority running the internet, it’s evolved down paths of least resistance rather than followed robust design.
Often bad stuff that can grow fast outcompetes and strangles good stuff that has some friction.

In r-K theory, you want an r strategy in the beginning and a K strategy once things are mature. The internet is only just seeing the first few K strategies emerging. It’s going to take some time for K’s to win, but eventually there will be few r strategies left.
