The EU has a new solution to this problem. With its 2024 Digital Markets Act, the EU is requiring platforms to furnish APIs - programmatic ways for rivals to connect to their services. With the DMA, we might finally get something parallel to the mobile "number portability" for other kinds of platforms.
If you've ever changed cellular platforms, you know how smooth this can be. When you get sick of your carrier, you set up an account with a new one and get a one-time code.

Then you call your old carrier, endure their pathetic begging not to switch, give them that number and within a short time (sometimes only minutes), your phone is now on the new carrier's network, with your old phone-number intact.
This is a much better answer than forcing platforms to provide service to users whom they judge to be criminals or otherwise undesirable, but the platforms *hate* it.
