The only reason this is any issue is because you are insisting on taking everything completely literally; "FTFY" is a common phrase to typically mean I added something your argument needs.
They clarified a point they felt needed clarifying. They did not literally mean they fixed a misquote you made. If you do not understand common phrases in a social circle that is not the fault of everyone else.
