Yep I saw that
Chess.com Makes Offer To Play Magnus Group

I think they will add Magnus bot. Nothing else,as Magnus owns chess24 and he won’t advertise other site I think
https://chess24.com/en/read/news/play-magnus-group-receives-chess-com-offer lol I thought Chess.com and chess24 were rivals. No friends. Not a good news to Lichess

I don't think it makes much difference to Lichess. They have a different business model that relies on donations. Folks tendencies to donate to Lichess is not likely to change based on what chess.com and chess 24 are doing.
I've been playing the play magnus app this morning and playing against little kiddie Magnus. I have beaten him up to age 8. I read that he was only rated 900 when he was 9 years old but started training with GM Torborn Ringdal Hansen and jumped all the way up to 1900 in one year.
