I feel like you answered your own question. “Yes, it’s still good for enthusiasts”. This is an enthusiast headset so the choice does make some sense.

Technically, this is the source:

https://mp.weixin.qq.com/s/ufib2bT-IM1WodZWKcmHzg

Bradley did say that he knows the person but he isn’t the source himself: https://xcancel.com/SadlyItsBradley/status/1976068955510132975#m

He also posted about some data mined strings referring to Deckard dv1 and dv2 which is presumably verifiable by someone: https://xcancel.com/SadlyItsBradley/status/1976141425801822419#m

You’re right to be sceptical since all of this is a mix of rumours, data mining and speculation. I think it’s fair to say, in this case, Bradley is more the data mining and speculation bit, rather than the rumour bit.
