.. and that's YT's problem? This is like being angry with Apple, because an app developer created only an iOS app and didnt create an Android. What did Apple do wrong if a developer chose to only create an iOS app?
YouTube is the system, you've not heard of "don't hate the player, hate the game"?
If I "blamed" the creators, you'd be telling me it's not their fault, they're just incentivised by the system, they're just playing the game.
But when I "blame" the system, you're telling me the system is not at fault, that it's individual choice to choose a near-monopoly on video discoverability that is propelled by and heavily benefiting from the same company's actual monopoly of search.
Is it "YT's problem?"? No, it's to YT's massive benefit, it's my problem when I have to suffer through adverts.
Alphabet is the fifth largest company in the world, has earnings higher than most countries' GDP, and is established to have engaged in illegal behavior as a monopolist. It's fair to say they're closer to "the system" than "a player".
Not that this was part of the suit, but the whole practice of giving things away for free and subsidizing them with stalking and ads obviously distorts or completely destroys markets, so yes they can be blamed for doing that. The behavior of these companies is so bad that people in a recent thread were claiming things like chat services (where a single computer can provide service for millions of users) cannot be sustainably run by charging money.
