From Cory Doctorow:

Here is how platforms die: First, they are good to their users; then they abuse their users to make things better for their business customers; finally, they abuse those business customers to claw back all the value for themselves. Then, they die.

Some of it is because we had a decade of cheap borrowing which has come to an end and many of these platforms were never profitable.

There's some talk about "a rise in anti-China posts that have hit Reddit lately" in https://join-lemmy.org/docs/en/users/07-history-of-lemmy.html, which struck me as odd.

Criticism of any governments should be allowed, especially authoritarian ones.
