I have to be honest and say, I don't even know what a "judgy host" and how it can matter.
As you can tell, I am actually using a "corporate" host, run by the Vivaldi browser people as I was already using the browser.
I have run into a few judgy people and sometimes they are correct, I should have alt-text on my pictures, but no I am not an expert at it and sadly it is not a super high priority for me to get much better at it. I have totally been dumped on from time to time for expressing unpopular opinions, but that is par for the course.
Oddly, one of the things I have been attacked the most for is when someone complains about Mastodon, and I make the mistake of saying, "You can really make your Mastodon experience anything you want it to be, have you tried (X,Y,Z). I have had people go absolutely ballistic on that.
And here I am saying the same thing again. I'm a slow learner, I guess.
