Are Playchess.com and chessclub.com still relevant in 2022 ?

I heard about the news of the acquisition of Playmagnus group by chess.com.

I was wondering if other competitors still exists or if it will just become a monopoly ? (aside from lichess)

Are ICC (chessclub.com) or Playchess.com still relevant ? I remember that a lot of GMs where playing there.

Chess platforms are like computer software - in the early days there were many options and lots of small companies with unique products. Slowly, some went out of business or were bought up by the giants like Microsoft and Apple.
We are witnessing the same in chess, soon lichess may be the only independent and free provider! It is good for the game to have choices and prevent dominance from a single organisation ... but wait a minute, isn't that we have with FIDE?!

Realistically, no. Neither of them are relevant in terms of online chess.

I don't know how many players are logged onto ICC right now but if you go to play.chessbase.com/en/ you will see some small text for their stats. I copy/pasta:

Statistics | Players: 1960 | Peak: 1964 | Games Today: 45559 | Nations: 151

Today they've had less than 2k concurrent users at their peak time (so far). As I type this sentence there are >90k players logged onto lichess.org - Keep in mind that today is a week day and it's early in the morning in USA - meaning 90k will prob go to >100k at some point today.

Having said all that it's generally a given that chessbase's offline software (ie. Chessbase 16) is generally the tool of choice for anyone serious about studying chess or preparing for a tournament. The reason being is it's database functionality (google it) and specifically it has very good database search functionality (ie. motifs, position, material, structure, theme etc.). I've never used SCID (its Free/Open Source) but I believe it supports most of what CB offers but lacks "prettiness".

ICC real business selling chess content I think as playing platform it close to dead was never very big. Free is hard price to play so they cannot really compete with chess.com in amount players hence commercial side has become pretty lopsided now

I thought ICC and CCA (Continental Chess Association) teamed up through chessaction.com to create a registration system (paid) for both OTB and online prize money tournaments. I could be wrong though, but I thought I saw it advertised in some chess magazines.
