well i don't quite get annoyed but i notice difference, or changes in usage, and then i get slightly annoyed if whoever denies that it is a change. do you know what i mean ?
eg, (i heard it again today on radio), something or somebody having been named for his uncle or saint's day.
we always used to say, named after...
similarly, his name is john but he goes by jack. that to me means he passes jack's house. we would say he is called or known as, or prefers to be called jack.
i don't object to the different form, and i guess it has come from north america, (anyone from there tell us please ?);
but people here in uk blankly stating, that's what we have always said. maybe v young people have, but not we oldies.
