As a Catholic, I blame ICEL. I don't know who you Anglicans are going to blame for deliberately sloppy translations from the Latin.
I don't know who/what ICEL are/is, but for the Episcopal church I'd blame those who created the '79, and those who voted for it.
Relatively recently I've encountered several situations where the '79 was in use, and have been appalled by the changes from the '28. Some day I should write them down. Or perhaps somebody already has.
Some parishes, including mine, have now gone back to "I believe". We also have been instructed not to hold hands during the "Our Father", although many still do (I'll be charitable and say it is an old habits die hard kind of thing, and they might not have been at the masses when Father instructed us not to).
