I agree with all of your points, all of them are Google's problem; not Free
Software's. If Google's Craptube was something more than a naked grab for ad
dollars maybe they would have designed it with users in mind. Craptube can't
be fixed, its broken by design.
Viewing videos on the site has been discussed at length here, most recently
in this thread: https://trisquel.info/en/forum/how-can-i-watch-youtube-videos
My advise is more straight forward: Stop using Craptube. Alternative means
for creating and viewing online video exist, until people support those
projects INSTEAD of trying to find the latest way to Jerry-rig Craptube into
some type of workable state that doesn't thrash their values nothing will
change.
This time last year I accepted this view, one I had for sometime. I also
realized I went most of my life without Craptube and it isn't a crime to do
it again. I haven't visited the site since.
You can't fix what isn't broken. Craptube does EXACTLY what Google wants it
to do and they owe us nothing. There is no point in "fixing" something Google
actively tries to break again and again.
