If they are breaking encrypted chats under an NSA gag order (quite probable) then they are required to lie, even in court or any (public) statements to the FBI. Homeland Security has special courts just for this kind of stuff but nothing that goes on in them is made public. So even if cooperation with the government is proven absolutely nobody is going to jail except the whistleblower.
Honestly, I thought everyone knew this stuff. It's why "canaries" used to be a thing.
Long story short: nothing you send on the internet is truly encrypted unless you do it yourself and even then there are no guarantees. Poisoning encryption standards is also also a known thing the government has been caught doing more than once. Encryption might stop your neighbour snooping on your WIFI but when it comes to what governments are capable of, all bets are off.
Having said that they're not going waste valuable resources like secret encryption backdoors going through your browser history and etsy shopping list. You need to be a pretty big fish for most of this to actually matter. I think a lot of people confuse capability with intent.
