Doesn’t this take up quite a lot of bandwidth if you have a lot of viewers?

Yeah it’s not just Microsoft. Fucking ads in my doorbell app, Google TV, etc.

Putting ads in a product you paid for should be illegal.

Invidious and piped had issues with youtube blocking them, but the instances I use work fine again now. They even blocked my self hosted invidious instance which I use maybe once a day lol.

Luckily Piped, Invidious and others are still doing its thing.
