Actually, according to Muslims, Uthman's intervention was for the 'standardisation' of the Quran so that the same copy of the Quran, with its specific zer zabr tashdid punctuations etc, was read across all conquered Muslim territories. The Quran to them was not corrupt but because of bad punctuation etc the words would start sounding a lot differently with different meanings.
So Uthman ordered the formation of a set standardised script and ordered all those copies that did not follow that script to be taken back and burned. Muslims will say Uthman did that to STOP the Quran from becoming corrupt in the future.
not according to several sources I have come across - the reason the Quran was burned was because it had already become corrupted, and there were many different copies in existance.
I think you are looking at some apologists wishful interpretation.
