>I can see no downside to changing it.

Yes there is. If you set a precedent that you're going to cave whenever someone says they are offended, you're going to attract trolls pretending to be offended so they can have a laugh at your expense[1]. The whole master/main controversy might be genuine, but it's only a matter of time before 4chan comes up with another word/phrase for whites to be guilty about, and therefore need to be changed.

Plus, the cost. There's no change without a trade off.

If you compare with the 10 000 ? work years gone into building news feeds where people scroll up and down looking at kittens and food photos?

To clarify, I think changing these words will take comparatively little time.

I just did some changes in a project I'm doing, and it's like 5 or 10 minutes work in my case.
