>I'm not sure how spoofing the GPS would impact other users in a negative way.
You could attack a pokemon gym at your convenience (from your couch, whatever time of the day). This negatively impacts other players because a legit, non-cheating spoofer will have to expend far more effort to do the same thing.
>Can you explain how spoofing GPS data so that people are allowed to play together even though they are not close is bad?
Friend interaction or just interaction in the game has to do with raiding and trading. You can already league battle (pvp) over any distance.
Niantic has made some changes along these lines - main one is the remote raid pass. One person close enough to a gym can invite friends to raid, no spoofing needed. They also upped the trade distance, how close you need to be to interact with a gym/pokestop, etc.
So the answer to your question is the game itself has made changes to address actual in-game scenarios. That leaves spoofing GPS as a way to asymmetrically cheat against gyms, or perhaps trivialize collecting pokemon (some are region locked and so on).
