I think the right question is: are they free cash flow-positive? I don't know the numbers off the top of my head. "Operating at a loss" means different things to different people.

Profit is an irrelevant metric for a company like YT that would reinvest every dollar of FCF into growth. (See Amazon for the well-fleshed out reasoning as to why this is so.)

The fact that they chose to operate at a loss for decades in order to unfairly monopolize market share is their own self inflicted problem.

You reap what you sow.

I'm not paying YouTube/Google one single dime. They already monetize all my private data and viewing habits.
