You are not getting the point and that you have such a naive mentality towards it is disconcerting because the consequences of your mindset breaking through as it seems to be has dire consequences for everyone, you included. You think dissidents have the ability to "post their videos anywhere else they want" but in reality the system that YouTube is deeply entrenched in and even essentially plays a leading role in actively attacks and sabotages and undermines those very alternatives you claim people can post things to.

This is not at all about the freedom of YouTube, it is about suppression of dissent and really the surreptitious persecution of dissidents.

What is really going on here is no different than when any other tyrannical regime disappears people in the real world, or even when the internet cries out in pain when, e.g., China silences people online. You may think they are being sent off to post and live on the internet somewhere else, but when they leave your sight form the bubble you live in, they are only then even more persecuted and attacked on a constant basis where you aren't even paying attention and are none the wiser to what is really going on.

In the end, "i told you so" will be utterly useless and worthless when the trap snaps shut and they come after you too once they have snuffed out and silenced everyone else they don't like, because this tyrannical authoritarian mindset is never satisfied and will always actively seek out new "dissidents" to persecute and one day you will find yourself on the wrong side too. It's just a matter of time, not whether it will happen.
