It doesn't bother me so much.
The key is that everyone uses the 'whole' registered name and not just part of it. Doing that should keep 'Wild and Wonderful' separate from 'Buddy's Wild and Wonderful'. I grow both.
Really, though, to me when a plant is registered under a name, that name is the equivalent of a unique serial number for a specific cultivar. Serial numbers are often very similar, using identical codes for make, model etc that are shared among many others. What makes the difference is the addition of something that distinguishes it from all the others. Adding 'Buddy' in front of the name does that. If it were the earlier of the intros, dropping it would be the same. That does require that the entire name be used because it's part of the registered name. Selling 'Buddy's Wild and Wonderful' without using the first word would be misleading and wrong.
Truthfully, that scenario is probably better than some plants that get widely distributed under the wrong name. People can grow those for years without realizing it. Assigning a name to an unknown without being absolutely certain (which is very difficult) leads to a lot of that. Careless mix ups at local sales do that as well. I think either of those are more likely to cause a wrong name to be used and both are rather common across the plant world. I have done it with an iris which I'd had for some time and purchased under the wrong name. It was a similar bloom that I had for a long time before I discovered it was parading under the name of another cultivar.
