I agree with this, but I think the impressive part about Lichess is that it's actually full of competitive users. Chess.com is, by all measures, the "default" chess application. But you still see active GMs and a huge playerbase surrounding Lichess, which enables them to actually have their very open structure + lack of annoying trackers as features worth peering into.
