These seem like valid but relatively minor complaints. YouTube should fix them. But the heart of the problem lives in the DMCA. If jerks or idiots file a fraudulent DMCA take down, the content comes down before you have a chance to dispute it. Then, even if you do dispute it... the DMCA says it stays down for at least 10 days. Ostensibly to give the claimant an opportunity to file a lawsuit against you, but there is no requirement that they actually do this, and your perfectly non-infringing content remains unavailable even if they never had any intention of doing so. (And if they do file a lawsuit then it stays down even longer... even though they've done nothing but file paperwork and have yet to prove
anything whatsoever.)
And then, after your content has been down for a week and a half and finally goes back up, any new set of jerks (or as we saw here, maybe even just the same old jerks) can come along and file another takedown against the same content and it goes back down for another ten days or more.
I would say that it's amazing it doesn't see more abuse, except that it does. SEO companies and similar such scumbags regularly file fraudulent takedowns against their competitors. As far as I can discern, the process Hollywood employs to decide what to issue a takedown for comprises some combination of untrained monkeys and a random number generator. Wendy Seltzer wrote a paper detailing a whole slew of other such issues a couple years ago[1] but still nothing has been done to address it.
