I don't believe slippery slope applies in this situation. For the most part Youtube has been fairly lenient as to which accounts get heavily moderated and/or removed. I may revise my opinion if it is ever shown that they become more aggressively restrictive to what is hosted on their platform - but for the most part you seem to be given a wide berth to upload what you wish.
The worst I've seen so far is that their video promotion algorithm can be used to "shadow ban".. but I personally believe they have every right to decide how their internal advertisements work.
There is also still the free and open internet as a general platform. Torrents and direct downloads are available as a distribution method if there is truly no other platform willing to host your media.
