What exactly is the benefit of typing out "Magic" the Gathering" everytime you refer to them? Wouldn't it be faster and easier to write "MtGox". It's not like people around here aren't going to know which service you're talking about if you use the usual acronym.
Are you somehow trying to say that they should be considered to be more legitimate, or more trustworthy, or more competent because their acronym represents some long company name from their past? I don't get it.
I decided in a post some time ago (I don't expect anyone to have read it) that I would deny "MtGox's" attempted rebranding. The rebranding was intended to distance themselves from their history as a trading card exchange. That history, to my mind, actually diminishes their credibility.
One can presume that their core exchange technology was not replaced wholesale during the switch to Bitcoin, so the rigour with which you might expect Bitcoin software to be written may not be there (you don't need bank-level security for a game card exchange). This is evidenced in the sloppy transaction handling, and more importantly in their
processes for fixing sloppy software. The patchwork attempt at repair over months, rather than a detailed effort to understand and analyse the problems, is a major factor in their downfall.
Bitcoin is by and large a consensus ecosystem. Their name is whatever we call them by, not whatever they say it is.
Maybe more people will get on board with going back to their naming roots if I stick to it pedantically.
Disclosure: I have not been harmed in any way by Magic: the Gathering's failings... at least not directly. No funds under deposit, no axe to grind except the pain of watching the fallout on the rest of the Bitcoin world.
