This doesn't necessarily follow but I can see how some people would get the idea. If you're running a service and a small amount of people on the forums complain about something that only happens in a rare condition (server queues being full for days on end) and your techs say that it's because their net connections are bad (this isn't the sole reason but it DOES contribute and is likely what the team was told) you probably aren't going to react that strongly to it. I don't believe anyone has ever looked as deep as they have in this case, they just went "we hate 2002 errors" to which SE replied "your connection might be/is the problem" and the subject wasn't pursued further because soon after queues would lessen and nobody would care again.
Technically if everyone's connection was perfect there would be no 2002 problem. As far as I can tell from everything everyone has revealed, SE and the users combined, is that every 15 minutes there is a very sensitive reconnect that happens. If your connection drops any part of that connection, the game considers you disconnected. The REACTION to that and followup protocol sucks and is poor coding it seems. However what I can assume happened, was the techs on SE's side all saw the server shooting back "this guys connection is dead, drop him" and assumed the cause was the users (something that's pretty common everywhere: nobody wants it to be their thing breaking). THIS finding was relayed to the "mouthpieces" of the FFXIV team and is what was announced. They were as transparent as they could have been, though maybe not as diligent. It's fair to say it was something that could have been fixed a long time ago, but it also has to be understood that until the perfect storm of problem happens, it wouldn't have been a priority in any company.
I think any further umbrage thrown their way is just salting wounds and sowing discord.
I think acknowledging that the company is doing the "right" thing with the information it has now and how they made a choice to act on user given information instead of ignoring it and continuing to blame throw is far more important than further shade.
