Nonsense. The publishers agreed to sell their inventory to Google, just as the movie studios agreed to license their content to Netflix or sell it on DVD.
Everything else from your post stems from this fundamental misunderstanding about how publishers monetize their content.

Then it's ethical for Brave to monetize The Guardian's content. It is not ethical for it to monetize everybody else's. The same with a piracy service. If a piracy service resells content it has an agreement from the owner to resell, that's kosher. It doesn't mean that it also gets to resell everybody else's content.

No. I'm just not stupid enough to accept Eich's stupid output.
