People whose thread model requires high stakes and serious encryption are probably using PGP with hardware keychain, with Tails or something similar on a live USB.
Adding a high-profile law like this will probably just cause them to increase their op-sec and make it even harder to actually get any evidence where it really matters, while having a huge PR cost and abuse potential. But it's very probably not about catching criminals anyway.
Also, it's kinda funny that they moved from SS to AA :D
