MISLEADING: "Apple Classifies 2011 Mac Mini as Obsolete"
There are two sections in this list:
"Mac products vintage in the United States and Turkey and obsolete in the rest of the world"
and
"Mac products obsolete worldwide"
It would be more accurate to say that the Mac Mini 2011 has moved to the "Vintage" list.
It is more than 5 years old but less than 7 years old. No they no longer have to make parts for it, and they've probably stopped which is why they moved it to this list. But, in California, and Turkey, they are required by law to have parts available and service available (of course, not free, but paid).
Can it still be serviced? Yes, as long as part needed is available somewhere, apple is not the only one to hold on to parts.
Will it still be updatable to new macOS's? The answer to that is: most likely, at least for a while. It depends on what hardware the core OS is written from. At this point, as I commented previously, I would say that, as long as new CPUs are 64-bit Intel, Apple could keep making installers for the same machines they've been making installers for since going full on 64-bit with the OS (64-bit hardware has been in Macs longer than the OS has been completely 64-bit based.)
This is clickbait, the headline is meant to stir people up because some feel Apple has taken too long to update the Mac Mini.
