If you're concerned with the new anti-encryption bill in the USA, there's a few things to do to help yourself a great deal later.
If you aren't already on a full-disk encrypted system running a FOSS operating system, go and get one now. Manjaro Arch, OpenBSD (or any BSD, really), Debian, Linux Mint, and so forth are dependable and secure operating systems. When installing, choose full-disk Luks2 encryption (with LVM if available) on install.
IF YOU ARE USING WINDOWS 10 STOP USING IT. BITLOCKER IS ALREADY BARELY BETTER THAN NOTHING, AND IT WILL BE THE FIRST ENCRYPTION SYSTEM TO FALL TO THE BILL IF PASSED. WINDOWS 10 IS INSECURE, UNSTABLE, AND UNRELIABLE NO MATTER HOW YOU LOOK AT IT.
STOP FUCKING USING WINDOWS 10! You are doing yourself less than no favors by using Windows 10. MacOS users, I'm looking at you too!
Keep up with your operating system's developer's news. If they state they are going to release an update in accordance with the bill, do not update. Even if not, turn off automatic updating if not already disabled. Every time an update rolls out, wait a while and pay attention to forums and other communities based around the OS, especially open-source development communities. If they start saying that their encryption has been compromised, don't update!
While not entirely necessary, I think it is worthwhile to keep a few full-featured installation images of other operating systems (full-featured, as in not the 'netinst' or 'minimal' versions) handy in case the developers decide to be massive retards and violate everything FOSS stands for by forcing an update that compromises encryption.
Format all of your removable flash drives (SD cards, thumb drives and so forth) to ext4 with Luks2 encryption. Not only will it be unmountable for everything but GNU/Linux systems, it will be as solidly encrypted as your own machine.
If you haven't done it already, download and install Tor Browser from
torproject.org, and learn how to use it properly. Additionally, Freenet, Onionshare, I2P, Gnutella, Retroshare, and so forth are quite useful. Tor is, in essence, the 'de facto' anonymity network. It's been time-tested since the nineties and penetration-tested by countless experts. While not foolproof, it makes censorship and deanonymization a whole lot harder.
What will stop this bill is widespread disobedience and anger. If the noballs politicians are shown that nobody with a computer system and half a brain will comply with such a ridiculous law, so much so to the point of protests and such, they might think twice.
