Well, people state all sorts of things. See font DRM claims before and
after Web fonts happened (without DRM).

The question is:
If DRM in browsers is available for video and audio but not for
captions and regulations require captions if audio is provided, will
movie streaming services refuse to stream movies to browser because
they couldn't apply DRM to the captions? Seems highly implausible that
the answer would be "yes".

In the Silverlight-based Netflix player, do the captions go through
PlayReady or not? If not, there's really no issue here.
