You can't satisfy every person on the planet xd There are always people with different view on different things... Amazon ads were 10+ years ago.... Snaps still but not everyone hates it. I don't for example. Canonical is a corporation which trying to make money. Of course. But at least they are doing it keeping Ubuntu free, and survive in this world where you can't do nothing without money. FOSS people basically pays nothing for things they are using. So it's nothing wrong Canonical trying to monetize their work.
