I'm not sure what to think, but that's definitely interesting. I wonder what chess.com is paying their engineers.
Even my diamond platinum extreme chess.com subscription (or however the third-best tier of a dozen or so is called) has much less functionality than Lichess's only tier.
With just a few employees, it is quite interesting to compare how much do some of these contributions cost, effectively affecting only a person or two, compared to a service like Lichess which is used by 5-10 million of users each month.
