I’m well aware revenue and profit arent 1:1. You’re “source” is a “Google person says they break even” in 2015. I give you graphs showing revenue growing at almost 4x the rate of users since 2015. Are they making 800% more profit, obviously not. But they sure as hell aren’t losing money on YouTube anymore.

Typed “was google profitable in 2022”. Took about 4 seconds.

Edit: as I’m not sure you’ll look at the graphs. I want to point out that since 2015 the “what could they have done to turn a profit” question is answered in the graphs

Users increased about 225%

Revenue has increased 700-800%

Its very profitable.
