Not really, Arrington presented anecdotal evidence, and Gruber smacked him down with a survey contradicting the anecdotal evidence. Unless some new evidence comes to light, Gruber's point of view holds more weight.
When I said 'they' I was referring to Daring Fireball.
My bad :-) Being a Daring Fireball regular, I just think of it as being Gruber - hence a use of 'they' indicates someone else for me. That'll teach me to pay a bit more attention when reading!
