Amnesty International has specifically criticized NSO specifically regarding UAE activist Ahmed Mansoor. He is currently serving 10 years in jail. UN human rights experts considered his arrest and imprisonment "a direct attack on the legitimate work of human rights defenders". He was monitored by the UAE using NSO technologies.
Amnesty International have also complained that they have been targeted with NSO Group technology - specifically Pegasus. They're currently launching a legal case in Israel to restrict their export license.
A separate case claims that NSO Group used Pegasus to help the Saudis spy on Khashoggi, who was brutally murdered in the Saudi embassy.
I don't think we need to argue about the bad guys in this case.
