Like when you send a .7z instead of a .zip or .rar to a friend or a teacher because that's what your computer has installed and they're like "Oh No, not one of those, now I have to install 7Zip" even though the same program that opens .rar also opens .7z I feel like people are way more annoyed when they receive a .7z
I wouldn't apologise for anything less than JPEG-XL. And even then, I know I'm right to help normalise it.
As if that person will apologise for trying to make me sign up to facebook or some other for-profit service.
