I think it's more to do with wrestlers not wanting WWE to copyright their original names so that they can go back to the independents (or AEW) and go back to their original names if it doesn't work out.
The name changes of pretty well known wrestlers is a little annoying (because we’re used to the old names) but when you look at it this way it totally makes sense.
Im not sure if im biased to the old names but the new names like Isaiah Scott for Strickland, Cameron Grimes for Lee and Joaquin Wilde for DJZ sound alot worse. Almost like jobber names
Bronson for whatever reason is a popular name for NXT wrestlers - James Bronson, Bronson Matthews and now Bronson Reed.
Probably the Tom Hardy movie of that name as they're all too young for Charles Bronson to be the reference. I'm the in-between age where Bronson Pinchot (Balki Bartokomous from 80's sitcom Perfect Stangers) is my reference point to that name.
