You know - that got me thinking - and it could be that they are saying that "ACH isn't being replaced" because people know what ACH is, and they don't want people to think they are no longer accepting echecks.
The general public isn't quite up to speed with MyEcheck as an alternative of ACH, MyEcheck isn't a household name like ACH.
Maybe that's why Ed merely said "I"m sorry they didn't like the PR". Perhaps what we read, since we know about MyEcheck so well, is different than what the general public reads, therefore saying that "ACH is being replaced" - whether true or not, is not a good idea to say.
