The only thing that would worry me is that he doesn’t have to love the FSB (used to be KGB), he just has to love not being thrown out of a window enough to comply with whatever they may wish, like oh say a Russian state owned Trojan not being detected by it or something. Not that they’re definitely doing that, but the possibility isn’t 0%.

I mean it’s basically the same reason I don’t trust much of the US based proprietary software, just %s/FSB/CIA/g, the only real reason to trust one over the other is if you trust either agency more than the other IMO, otherwise distrust both.
