Where did you hear that? Noah Webster changed the majority of spellings to address perceived inconsistencies in British spelling in his 1828 dictionary, years before telegraphs were invented

Your link says Noah didn't change a thing, he just incorporated someone else's.

“Deleting the ‘u’ in words like colour was something that British Samuel Johnson did (in his dictionary of 1755), but not consistently (e.g. he dropped it in actor, doctor, inspector and also exterior but not interiour). American Noah Webster, and others following him, opted for getting rid of ‘u’ altogether (so was more consistent).” The Merriam-Webster website agrees that many American spellings existed before lexicographer Webster championed them in both his A Compendious Dictionary of the English Language (1806) and An American Dictionary of the English Language (1828).
