As someone who uses Debian for their own home server I was interested in reading this person's experience, but they seem to have filtered it through an LLM which added a lot of words and not a lot of insight making it significantly less readable in the process.
Ultra-low-sulfur diesel became mandated in 2006 as the only type that was legal to sell for road use. That requires extra refining to remove the naturally-occuring sulfur from the fuel which is why the cost went up.
The answer is pretty obviously AV1 if you care about delivering content to actual end-users, unless you expect them to be severely bandwidth constrained. AV2 is still not mature from an implementation perspective; I wouldn't consider it ready until at least the dav2d software decoder has had time to mature, which the project page implies is still in a fairly early stage of development (they still list "complete C implementation of the decoder" as a "on-going": https://www-test.videolan.org/projects/dav2d/) and I am not sure if any encoder exists besides the AOM reference implementation (which was notoriously slow for AV1, so I assume the same for AV2). Furthermore it will be years before hardware AV2 decoders and encoders make their way into consumer products (this will likely be further delayed with the current shortages of memory and storage chips causing hardware lifecycles to be extended even more than they already had been over the past decade).
Why shouldn't they get 6 MHz? My PBS station broadcasts 4 subchannels: the main PBS channel, PBS Kids, a channel with programming about our local region (which airs live coverage of our state legislature when it's in session), and a loop of weather information with audio from the local NOAA Weather Radio broadcast. Those are all useful public services. PBS Kids in particular I think has a very good reason to exist, considering the absolute wasteland that is young children's media on streaming.
