YouTube will not change until people stop using it. And people do not want to put up with the inconvenience of not having a YouTube type service again for the amount of time it would take for YouTube to change or a viable competitor to take their place, it really is that simple.
Are YouTube and Google terrible? For sure, but it only got this way because the only backstop to holding them accountable, the consumer, has proven that they will choose putting up with shitty products and services in the name of convenience 9 times out of 10.
Same reasons that ad tiers are gaining a foothold in streaming services like Netflix. The consumer has shown they are fine with it.
