Youtube seems to be fighting with video downloads? I receive "sign in and prove you are not a bot" every day when using Tor (and without Tor YouTube is not accessible). I don't mind watching ads or solving captchas but Youtube chose the worst method.
You know, the YouTube app on my Amazon FireCube recently started prompting me to log in every time I open it. I don't have to authenticate or anything but I do have to choose a profile.
This started a couple of months ago and I didn't really think anything about it. However, it appears as if this behavior might have been a precursor to this new DRM initiative.
Every day, YouTube gives me more reasons to avoid it completely.
