I would argue there's a difference between natural language change among natives and language change because learners can't/won't learn something right. What we're actually seeing isn't language change, but language shift (in the Gaeltacht), where Irish loses all that separates it from English as English creeps in, and language formation (outside the Gaeltacht) as a sort of Gaelo-Anglo pidgin/creole is being formed.
I'd expect people to not want their Irish to sound so like English (jibberish English like the Simms) but it doesn't seem to be something learners or educationists care about or are aware of
The biggest problem with the latter is a lot of learners don't grasp the Slender/Broad consonants distinction at all (it's a palatilization/velarization distinction similar to the soft/hard distiction in Slavic languages).
