Long time YouTube channel Machinima, which started out as a home for videos done with video game assets but evolved into a regular video channel and multi-channel network, surprised a lot of people by leaving YouTube. This is because of the acquisition by Fullscreen, after parent company Otter Media was taken by WarnerMedia. Unfortunately this has led to headaches for the independent creators who had been working with Machinima and are now scrambling to regain their content on their own channels.
Also Machinima was the production company who made the Prime Wars Trilogy set of Transformers cartoons and with Go90 down (I wish I had known) I can’t finish watching Power Of The Primes and there’s no word of any of the three series getting a home video release. This is why I prefer physical media!
