How to move away from Big Tech Online Gaming Platforms
Here's a guide on how to easily get away from Chess.com and Steam.
Users can't move games purchased on Steam over itch.io unless developers offer keys for both platforms. Steam reward points can't be migrated either for obvious reasons.
If you move your chess activity from chess.com to Lichess, consider exporting and importing your studies and game collections. You can't migrate your ELO rating though. But that can be a liberating thing. It's nice to start fresh and you'll probably end up with a higher ELO on Lichess at some point anyway, as the rating inflation is higher than on chess.com
