"Nintendo" (which used to like his vids) apparently sent him a Cease and Desist letter demanding he stop using Nintendo references on his channels. Well apparently using the human puppets was not enough and now he said all his channels are being taken down June 1st 2021 which is tomorrow! I wish this was a joke but it's not, here's the proof! https://www.youtube.com/sml/community
I kind of wonder whether it was actually Nintendo or if it was really someone else trying to fake excuses to wipe out all remaining channels that aren't directly under the control of Google Inc. We know YouTube hates SML's guts, and in the past 2 years especially we've seen most of the old YouTubers quit (ExplodingTNT, PinkSheep), get rebranded by YouTube Inc. (SMG4), or get demonetized or terminated for no reason, to be replaced by completely obvious plants and hired YouTubers who instantly gain massive visibility with zero effort (Dream). Google probably knows SML is the last major remnant of pre-monetization YouTube, and while he too likes big bucks he's too stubborn to bend to their wishes all the time and won't make videos just to help them make more money. Everyone else who isn't part of the marketing scheme is either dead or buried below everything else and never sees the light of day, SML being one of the last survivors from the old days and they know it's not advertiser-friendly nor good for their desire to control everything like 1984.
