DMCA works on a "takedown first, ask questions later" basis. Therefore, the solution is to flood YouTube and Google with massive, frivolous DMCA requests targeting the creators of DMCA like Microsoft, Apple, and Disney. They'll solve the problem if it affects them, maybe.
DMCA is for user generated content on platforms, so microsoft wouldn't have a lot of surface-area to target. That said, youtube gives preferential treatment to the largest creators and companies. Apple and Disney could easily call up their manager Jerry at Youtube and deal with frivolous takedowns. Small creators often have no direct contact with a human at youtube and have X as their best option for contact. Unless they know the process and have enough money for a lawyer, they're shit out of luck.
Large companies just sue people who make false DMCA claims, but small creators cannot afford to do that when large companies make false claims about them. It is a biased system.
Seems to me like it's still fraud, by definition? If you monetize your content you can prove loss, if a competitor is engaging in the fraud even better!
Those people being targeted by this troll should band together and sue.
Maybe I'm just a malcontent, but for me this begs the question: couldn't this be used in reverse as activism?
Like, if enough people used enough fake accounts and started relentlessly submitting takedown requests on the biggest channels making the most revenue, not only would YouTube start to see the revenue issue, but the big channels would start making noise. Go after one troll sending the requests, another one takes its place. Seems like it would force YouTube to at least reconcile with this particular flaw in the system.
