I'm sorry, but I really don't see this in any possible way. Can you help me understand? What did he say that you consider "trash talking open source software"?
The reason I like him is that he's been fighting Apple anti-repair policies for years.
The problem here is that he's attacking the general case of free software licenses - OK I get it that some people downloaded a malicious fork of Newpipe and that sucks. But that's not a reason to abandon free/open/copyleft licensing of software, which is essentially the case he's making. At the end of the day this is a guy who has a large audience and has decided to attack open source licensing. I get that he may be a good guy and do other things that are good but that is a serious problem.
