It sounds like you don't really agree with the sentiment in the comic, if you're asking that question?
That being said, there exists no innate right for content to be hosted on Youtube (or anywhere else for that matter).
Perhaps the two align, I do not know. Until more is know, I reserve judgement.
When this comic was first printed it was partially a response to big platforms like Reddit having massive waves of bannings. It has always been about systems that are advertiser friendly, even if Munroe is too dense to realize that.
Automated content flagging by AI on a platform like YouTube is completely different.
The reality is that speech is ALWAYS a slippery slope, and those who believe it isn't are always surprised when they become the next target.
