I think EncroChat scared them pas-de-merde, and this may be an overreaction by untutored civil servants.
Once it became a big enough target it got taken down, and then quietly run by the police who collected everybody's messages for months before triggering a huge round of arrests, including quite a bit of major organized crime across Europe. The dangers of centralization. They'd love another EncroChat!
Doesn't apply so much to GrapheneOS of course since they're not in the messaging platform market, but it's definitely a cautionary tale.
Huh?
"Scared them shitless" in faux franglais.
Probably something like this would be close to the same colloquial meaning (I'm not familiar with any pants-shitting slang in French): EncroChat leur a foutu les jetons de ouf.
(closer to "scared the hell out of them")
