I can't imagine the frame of mind the author has to be in to think that there's moral value in not "naming names" of corporations that do things badly, as if they are people who can be offended. Although they also write cringe things like "to the builders <heart emoji>" so perhaps I will just never understand them.

I think it would distract from the points he's making. The article could be misread as a rant about a bad time he had, when it's actually meant to make a specific point about considering async vs sync transactions and what happens when they're combined in the same system.

And I don't believe that only one streaming service and one bank makes such mistakes.

There’s a lot of bleeding heart people like this. They add variety to the world. The downsides being things you mention, but it’s usually more palatable than someone on the other end of the spectrum.

Sometimes they're worried about getting sued.

I don't think its for moral value but rather they want to make a general point. For example Netflix couldn't care less if they were named or not named in this blog so what purpose is there to "name and shame" them? Most normal people dont even know what a request is so its not like there is any reputation damage risk here for Netflix and the author can write without any bias and talk about general tech and its shortcomings/quirks.

That is the frame of mind and seems pretty reasonable.
