That has nothing to do with respect. On the other hand, if you "respect" organization's spelling choices, you end up with abominations like "macOS". It's better to make a habit to ignore them.
Or if they did, the complainers weren’t important enough to matter.
Just be thankful that they didn’t name iMac MacMan.
That's a stupid name but at least it's a valid word.
But if an organization (for whatever reason that might happen) wrote about me, I'd expect them to capitalize it properly according to their style guide.
