While that's true, it's sad that the default expectation seems to be "you provide support for me and keep maintaining this thing, and once you can't anymore, you'll find somebody else who does, so that I can keep benefiting for free from all your work".

The default expectation should be that there is nothing promised beyond what's in the license. Anything beyond it needs to be clearly stated, but in the absence of any such statement, don't assume or expect anything.

Note that this expectation is clearly stated in most FOSS licenses. Usually right at the top, IN CAPITAL LETTERS. Having to write an extra blog article that basically says "I really mean what is in the license" is redundant, and it's sad the this has do be done and is even being argued about.
