(not OP) lichess is free software, it's free software that works, it's community supported and sustainable. chess.com is a mild piece of software and a company that splits its time between trying to be a business and trying to provide a good chess experience. I'd prefer more of the former to exist.
I like the lichess story a lot. Last time I read an interview with the guy running it, and I really appreciated his attitude towards his service and to what it represents to people.
