This comment is very surprising to me. I don't think it's reasonable to expect any three-letter acronym will only mean one thing. For example my usual nickname has three letters, and has around 20 definitions on wikipedia, including sex-related, drug-related and politically charged meanings (I don't identify with).

In fact, DID already has a disambiguation page on Wikipedia: https://en.wikipedia.org/wiki/DID_(disambiguation). I don't think Dublin Institute of Design or Data Item Descriptions constitute "a wholesale theft of a language".
