To be fair, I'm pretty sure by "analysis" they mean "engine analysis" (since that's the part you have to pay for on chess.com, not just getting an analysis board of your PGN). On lichess, "Analysis" is one button, but "Request Computer Analysis" is another button _in_ the analysis screen, and its often below the fold and behind a tab on most display resolutions. Probably because even fishnet wouldn't be able to keep up with deeply analysing every game on the site, and the in-browser WASM stockfish is good enough for most blitz/bullet games.
