I don't quite think you don't notice it. You hear it all over the place, see things moving all around in every pavilion that it exists in. Everywhere you step the sounds of the countries themselves are lost to a sea of voices from Doofenshmirtz to Carl to Major Monogram. It's also one of the only things that has really "intruded" on the World Showcase from what it originally was.
Selfishly I'd rather it go back to being about the countries themselves. I now spend what little time I get in WS running around after my kid looking for the next trigger event, instead of actually taking time to enjoy the pavilion itself for what it is.
Easy to control that one I guess is just say "no" to the kids, but that's where the statement about my kids stoning me came in. They love it.
All things considered, there are 1000 things at Epcot I'd rather see them address first, as you mention, all things considered, this is pretty innocuous.
