Well a lot of people expect everything to be free too.

But while I can afford to pay for my email provider and a few services, there is a large population that is struggling to even pay their rent.

Youtube is definitely bringing back a profit to Google. Probably not huge, but definitely far from 0% return.

Now they did have to shove way more ads in there to make it happen.

Having an acceptable ratio between ads and a big media storage seems pretty much impossible, unless subscription based which most people can't really afford.
