There was a famous Black dude whose name I don’t remember, but he of his own volition managed to deprogram a whole bunch of KKK members.

His name is Daryl Davis. For anyone not familiar, he has some great videos about this on Youtube/proxies.

Is sailfish OS even maintained?

The latest release is dated 2024-09-20, so it appears to be. I haven't used it myself though.

Yes, it does. I've just checked and confirmed the presence of /usr/bin/lsblk on a Debian 12 liveUSB.

Edit: formatting

Or just use lsblk.

It looks like it may need to be charged, or the OS is corrupted somehow and needs to be reinstalled (source).

For SailfishOS the lock screen should look like this.

Here's a list of public SearXNG instances.

Or even just use any public instance found here. Different instances may have different defaults, but under Preferences you can enable/disable whatever search engines you want.

There’s a masterlist of searx hosts somewhere, I’ll try and see about finding it if someone else doesn’t link it.

It's here: https://searx.space/

At this point I think that I'm probably safe to get rid of my old cat3 cable, but I'm keeping everything else.

No, it's only a bad idea if nothing else is allowed.

That article is poorly written. This one is more informative. Since there's a paywall, I'll quote a few relevant parts:

"China has introduced new guidelines that will mean US microprocessors from Intel and AMD are phased out of government PCs and servers, as Beijing ramps up a campaign to replace foreign technology with homegrown solutions.

The stricter government procurement guidance also seeks to sideline Microsoft’s Windows operating system and foreign-made database software in favour of domestic options."

...

"Officials have begun following the new PC, laptop and server guidelines this year, after they were unveiled with little fanfare by the finance ministry and the Ministry of Industry and Information Technology (MIIT) on December 26. They order government agencies and party organs above the township level to include criteria requiring “safe and reliable” processors and operating systems when making purchases. "
