Incidentally the same labels make Gmail fundamentally incompatible with the way IMAP works causing lots of weirdness whenever you use any standard email client not specifically designed for Gmail.

How does an offline installer from GOG differ from the offline installer provided on a CD/DVD?

This is equally true for almost any game ever sold, including physical ones. You only ever own a license that specifies what you can and cannot do with the game. The difference is in what this license is tied to, for example either a physical copy of a given game or an account that can be remotely deactivated taking away all your games. In GOG’s case once you grab the installer, the game license cannot be easily forcibly revoked, just as with the physical copy.

Frankly that’s something I do not understand. Why this single specific word? We have dozens of terrible offensive words. Why this specific one is considered so bad we cannot even talk about it directly, even when merely discussing it? I would think discussing it and not directing it at someone would be pretty reasonable. As with every single other word.
