Simple File Manager (and the other associated apps) got bought by a company, so this is a fork by a long-time maintainer that keeps it FOSS

I use MiX, which has a "Search local" option when adding SMB, which sounds like what you're after
It doesn't have to be live, you can make backups and put them various places for redundancy, so that it can be restored. A backup is small enough to fit in some free cloud storage, preferably encrypted, which helps protect against a few eventualities.
BIFL and Bluetooth are typically an impossible combo because Bluetooth means more batteries and electronics to break/be unreplaceable. Maybe modular systems will come in the future but they'd need to use a completely generic set of batteries.
My best suggestion, based on what you describe as your problem with wired headphones, is to get headphones with a removable cable, as those cables are generally pretty standard. I know sennheiser had a lock in mechanism but you can get third party cables. Also, I was able to take that out of my HD599s and use the headphones with a Bose cable.
The title here said E2EE is made impossible, I was simply saying that is untrue. Clarity matters. It says in the article they removed the bit about banning encryption or requiring back doors to it before it passed.
The rest sucks, as I acknowledged, and they want to make it easier to scan devices that would include messages that have been decrypted upon arrival. There's already spyware they does exactly that. However, that doesn't make it so that E2EE is impossible.
This is openly misleading. This sucks, sure, but it doesn't ban e2ee as the title suggests.
I think it's all speculation so far, but I've heard the company is an analytics one, so it's likely to try to sell user data
