There was a confusing name change, and it doesn't help that ecdsa/ed25519 has two names, but the number 25519 is specific to this fixed version. Funnily if you quote search nsa and ec25519, this thread is the only result besides one ycom thread (which also is in context of them being safe).
ec25519 is not a typical name for it used in any software afaik, only in writing.
Edit: Historically ecdsa used to refer to the backdoored one. Since it has fallen so much out of use, ecdsa now means ed25519 since it's usually imcorrecly called ecdsa and also changed to ed25519. It is of course better to specify 25519.
