I like the idea of Piped, because I could use it with LibreTube and have same subscriptions on different devices. But since Piped doesn’t work at all for me for the past week, I’ve switched to FreeTube. It works with no issues.
I don’t see them blocking accounts. What would it achieve? Their goal is to monetize you. By taking you out of the equation, they can’t monetize you anymore. You’ll probably keep doing what you were doing anonymously or with a new account, so blocking you won’t reduce costs either.
On the other hand, Google is collecting a lot of data. Maybe now they aren’t using it very effectively, but sooner or later they might find a key to make YouTube Premium a viable option even for someone like you. By using YouTube and other Google services, you are providing key fragments.
How does this help reducing noise? I think with modern cars, tires generate notably more noise than the engine unless the speed is below 30 km/h. I hear no difference between a petrol car and electric when they’re driving past me at 50-60 km/h.
