Don't buy blueray discs and don't use Midori, don't use any content at all that is DRM encumbered.
Yes, that will limit your choice but so what, if enough people do it the coin will drop.
That's my solution to this whole DRM issue and I've yet to find a 'must-see' thing that was DRM encumbered.
Copyright law gives rights-holders all kinds of options, and digital tools have given them options to make it harder to do some things that are not per-se violations of the law but that are also not explicitly granted as rights.
And that's a huge difference from a legal perspective.
