You actually don't, because this is in the Linux Kernel. Fine if you don't want to, just like I don't want to have anything to do with Epic Games. But this is a personal and emotional decision, and I do respect this!
However, charity washing? Is this conspiracy of something? I mean they develop an Open Source software, controlled by the standards of Linux. So from security and privacy standpoint there should be no issue. And I don't see any problem or issue. If someone could explain to me what the problem here is, I might change my opinion (and trust me, I do change my opinion). I just don't see an issue here.
