Could chess.com do a collaboration with lichess?
What makes you think there isn't already one? Do you think if people thought in a sector that there was a hidden monopoly, that it would end up benefiting the two market leaders? What makes you think any answers to your caustic answers to your q would even be viewable here? Did you know this is a for profit site? Did you know that lichess has code allowing time-based analysis to check for poor time management in a game analysis, but that the code isn't active? Chess.com has that. But, we get to pay for it. Clever, no?
