The automated system you're talking about is called Content ID and is "not DMCA".
DMCA is a legal statute, which is where copyright holders expressly file a notice to YouTube that they're hosting infringing content, and getting one as an uploader will lead to an account strike.
Content ID is completely separate from any legal mandate (besides the settlement Google made with Viacom). In fact, it's even separate from Copyright entirely; YouTube is under no obligation for Content ID to operate only on copyrighted content. If YouTube was willing, they could take a paycheck from Disney to keep Steamboat Willie stuff protected by Content ID, since it's their own system and their own rules.
For this reason, the process for Content ID appeals is tougher - it's in YouTube's best interest to keep videos claimed, particularly if they need to appease rights holders[0] who hold all the cards for whether or not their music is available on YouTube. If it were a DMCA notice instead, you would have a legal right to counter the DMCA notice (under fair use) and get your video reinstated, unless the rights holder tells YT they have filed suit against you.
I am well aware of the differences between the two, and this is exactly what I was referring to. There absolutely have been instances of bogus DMCA takedown notices negatively impacting users and being a nightmare for them to resolve.

I never criticized YT for this (stating that Google hardly cares to hear is just a fact, used as an example - they are notorious for not putting much effort into responding to customer service complaints), I just used it as an example of one platform on which this happens. The entire point of my post was to highlight the fact that bots scanning for copyright infringement don't typically care if your voice happens to sound like, say, Gilbert Gottfried. All the bot hears is Gottfried's voice, so bam, takedown notice sent.
The platform doesn't matter.
