I don't know the stuff from the malcony guy but after a quick glance at their Twitter it seems like they mostly use motions from other creators, because I recognize some of them. A lot of animators also use models that were freely shared by others too. So if they use the motions and models of other creators I feel like at some point it's not really "their own work" anymore. I mean sure they still put it together themselves and that's some work, but it's a little rich to be overly protective and butthurt over people pirating your stuff when you already rely on the free work of more skilled and generous creators to even be able to make anything in the first place.
If that's paired with an unreasonable payment requirement to get the content the legitimate way, like it is the case with the cobby guy for example, who requires you to be subbed for two months in a row for some videos and others require you to have supported him for an accumulated amount of over $300, then I don't really have much sympathy for them trying to "protect their copyright". I don't even think you can get all their past works legitimately because he arbitrarily limits access to them after a couple months, quite literally making it a requirement for people to pirate and share the content or otherwise it becomes lost media.
Thankfully the majority of creators are much more generous and only require a simple fairly cheap payment to access most of their works and if you really like some creator you should support them since they deserve the money for the work they do.
