I don’t think they meant OSS per-se. I mean, compare Google services with a popular f2p game like Valorant. Google mines your data to target advertisements at you on a psychological level. In Valorant, you can spend money to make your gun look cooler.
I think the latter business model is very respectable because it’s not sneaky and it isn’t manipulating me nearly as much. You can have hardly any money at all, play on a crappy computer, and still have a huge amount of fun in the game. You could even be very competitive. And all for free! Not even at a cost to your privacy! And you can optionally “donate” money to the project if you want to support the game and get a neat cosmetic. How is that not a great business model for me as a consumer?
