Is it that impossible for you to imagine that someone could be extremely apalled by the invasion of Ukraine and be fully in support of their side (i.e., being fully opposed to the Russian side), while at the same time standing for the principles of open internet and not believing in wholesale disconnecting entire countries?
Because that's my personal stance. I am fully on the side of Ukraine here, with no "ifs" or "buts", and I simultaneously don't believe in blackholing tens of millions of people like that being a good idea.
If MEGA is used repeatedly and almost exclusively by threat actors as an exfiltration point, and is unwilling to address legitimate concerns about their use across the web, why shouldn't every who isn't interested in using MEGA just block any connections to or from the service?
