V3 uses Discord.py rewrite, so I think the goal here is to be consistent. From the docs for the rewrite:

The official API documentation calls the “Server” concept a “Guild” instead. In order to be more consistent with the API documentation when necessary, the model has been renamed to Guild and all instances referring to it has been changed as well.

I think it was decided that guild was to be used in the back end, and server in front.

Discord calls them servers in their own UI while the API docs refer to them as guilds. Thus, I think it makes sense that they should be referred to as servers with regards to user-facing output and as guilds otherwise
