Enshittification means a lot more than just "we made it worse". It's more "we got in a position where we could make it worse, and nobody can do anything about it". Of course I oversimplify it a lot, I just can't say it better than Doctorow.

Again, I suggest you watch that 39C3 talk (it's like 45min?) because Doctorow talks really well and it's a very good introduction to the problem. His book goes into a lot more details and gives a lot more examples, but I understand that it's already almost impossible to get someone to watch a 45min presentation, so reading a whole book is out of the question for most people... :-)
