are you sure about that?
Who else think chess.com is pay to win

I pay chess.com so they can build an algorithm to bust cheaters. To me it's one of the more important things in life, because whoever cheats at chess, wants to cheat in life as well...

Seriously, what is wrong with you. Others have already mentioned it, but there is zero 'pay to win' in chess. You are wrong. Period.
The question remains why you feel the need to promote a competing website? One that is already known by all active chess players (many people use both even, I think). You pay for services offered, not to win. I find really difficult to imagine someone not seeing the value of what this website is offering.
I get the first part, but I don't understand what you're saying about promoting other websites and what this website is offering. Other websites are offering the same stuff but unlimited and free.
well i mean chess.com is yes and no pay 2 win. I mean you can have a better experience if you pay, but i meannn who cares man? i mean i think for me only cause i use lichess more often-

i sometimes feel that [another site -- VP] is way better than chess, because i can do analysis for free there
We can analyze for free here, too.
https://www.chess.com/analysis
Free. Boom. There we go.
something tells me that other site is lichess . org
and yes chess.com is p2w the only reason why i have diamond is because a family member said they would pay it for me
chess.com locks everything behind a paywall and i recommend using lichess
lichess has like 0 players tho
