You could still subvert this by taking an actual picture of the screen with a camera I think.

#12How to drive away customers: prioritize your unproven loss of income over making an attractive product. Accuse all your users of copyright infringement.

#13Take a few screenshots, until you get one image with the odd lines, and one with the even lines, then stitch them back together in Photoshop. 2 minute job, tops.
2 minutes is quite a long time. Long enough to not bother unless you really want that particular image...

#15That looks terrible in Chrome for Android.

#16And oncw again if your user is a developer he'd or she'd be able to stitch it back together.
That was not the point of the article. In fact, had you read the article, you'd find that your point has been addressed three times over and that the author acknowledges it's all futile anyway.
I don't think he quite does. His conclusion is basically that image protection isn't worth it, because more exposure is better. That's different from declaring it to be futile.

#19That demo messed with my eyes. Even though it is interlacing faster than the eye can see for some reason it still felt weird to look at it. Overall, not worth the trouble or the decline in user experience.
Wouldn't surprise me at all if this technique is seizure inducing.

#20Why would anyone want to do such stupid thing? It would prompt users to bypass it just because. And there are tons of ways to make a series of screenshots or even a video of the screen.
Ksnapshot, imagemagick (import), ffmpeg, avconv etc. etc.

Let's assume DRM is a dumb and nasty idea which always leads to very crooked practices. Period. As if we don't have enough of this EME nonsense.
