Not at all.

If you want to use PGP for encrypted email, and they supported it e.g. in their webmail - that would open them up to being a valid 'target' for the new bill, to provide access to your encrypted messages.

If they're just a conduit for your PGP (or even S/MIME) encrypted messages, the government can compel them all they like - there's literally nothing they can do to decrypt those messages.

Note: I am not a customer, or involved in FastMail at all (I am Australian though). This is just one of the facets of encrypted email IMO - if it's decrypt able somewhere between your laptop/phone/etc and the other persons laptop/phone/etc, it's not end-to-end encrypted, is it?
