Oh yes, I know open source games existed, but did any raise enough to pay wages of a team?

ps. I personally played Threes first, which 2048 copied without the style and made free. I admit I was slightly disappointed for the original devs that the copy became significantly more well known. It wouldn't be my first example of the benefits of open source.

Full team, no. Probably not even just the one guy who made 2048, unless maybe you count minimum wage. It's hard to know what he earned of ads and such, but I can't imagine it being anything massive.
