An edit was recently made to an answer I posted to this question:
The edit changed this text:
That would change its orbit (and its influence on the other moons) in unavoidable and easily observable ways.
That would change its influence on the other moons in unavoidable and easily observable ways.
It seems to me that the editor believed my answer was in error about Ganymede's orbit being changed. Whether or not they were correct isn't especially important to me...but I was surprised that someone would just go ahead and edit my answer to change its meaning/semantic content. I thought edits were supposed to clarify a question or answer, or to correct grammar/spelling/punctuation etc.
(I would have thought the correct way to challenge the accuracy of an answer or part of it would be to post a comment and dialogue with the answer's author.)
Is it appropriate to edit someone else's answer in this way?
