It's also not that that tech is only used to oppress free speech, hunt down dissidents etc. I was tangentially involved in an investigation targeting a child pornography collector/trader and talked a bit with the lead investigator. Their department used a commercial trojan as well, though I don't know whether it was built by FinFisher. "Hey, want to help us take down people that rape children?" doesn't clash with moral principles for most people, I think.
