I don’t see a chance that ISP(s) will block access to you tube or the related..
It will be a stupid move, since youtube do not contain porn or any other harmful content.
Moreover.. they did try to block People from using Torrents (Here in Israel..), in the past.
It did not work (And this is purely illegal to use torrents..), and they took the leash away eventually.
Even though some ISPs here are partly blocking ports belonging to torrents / Emules.. that only makes the competition richer (Isps that do not do that)… so blocking youtube will also be silly business act…
