Canada also has private copying (and pays a levy on blank media to pay for it, although at this point we're pretty firmly out of the blank media era).

(What a classic Canadian government URL that is.)

Does this mandate American companies provide a mechanism for a personal copy ?

In theory YouTube could geo lock these features if made to implement it.

No, unfortunately, and DRMs are still legal. Which is a shame given that we have to pay a tax to the copyright industry whenever we buy a storage media (be it an SD card or an HDD) in exchange for this right…

What I mean is that there's no legal reason for Youtube to prevent downloading their videos (they can't be sued by IP holders for providing a download link for that matter).

So does that mean if you watch Netflix in Canada or France you can send a letter requesting a copy of their media ?

It seems like a good idea, Bojack Horseman is probably going to be taken down at some point, but enforcement remains elusive.

You can send them a letter, and they can comply without infringing any agreement made with the copyright holder, but they don't have to.
