So fwupdmgr takes care of this on the command line?

My mind was making one transfer to much, as the opinion clip in German TV news is called comment. There were no additional downvotes after I added the second sentence for clarification.

Obviously the naming is not consistent among the wikipedia articles in different languages:

Intelsat 33e war ein kommerzieller Kommunikationssatellit des International Telecommunications Satellite Consortium (Intelsat) mit Sitz in Luxemburg.

https://de.wikipedia.org/wiki/Intelsat_33e

Its named after the * International Telecommunications Satellite Consortium*

I was talking about Intelsat 33e which ~~is~~ was a communication satellite, not for espionage, on a geostationary orbit. The russian espionage satellites Olymp-K and Kosmos 1408 mentioned in the other replies, however are/were on a geosynchronous orbit and on low earth orbit, respectively, as you suggested.

Yes, since Bookworm, there is also non-free-firmware which before was located in non-free. I've skipped that for simplicity, as both follow the same rules and non-free-firmware was introduced basically for convenience.

Do you know if either of the non-free repos contain binary files without having the source available?

I know it does, that's why I was curious about the novelty of that approach.
