There are a few hundred other examples to pull from, these are just a few I chose at random while trying to select ones that are more about the code, or terms used in the code, than contributors or maintainers of the code.

I found some of the requests to be pretty reasonable. Some were reasonable, but not very pragmatic. Some just kinda elicited an "eh, come on?" sort of response.
I then started browsing through my own code to see if anything seemed offensive. One thing that caught my eye: in SPI communications, there is very clearly a "master" and a "slave". I have programmed many SPI-related code... So now I wonder, what was the original complaint in calling Redis servers "master" and "slave"? That terminology is very, very common in computers.
EDIT: I guess this is the original complaint?: https://github.com/antirez/redis/issues/3185
EDIT #2: I guess I'm late to this conversation: http://antirez.com/news/122
