I could see a few situations,
a. The link is wrong (though it seemed informative so I'm not immediately for that, and it seems right... Because I've had games survive worse on less*, the queue seems aggressively sensitive)
b. Someone informed Yoshida wrong
c. They know the reason but it is providing relief and so they were trying to hide it, as they don't want the queue to be even longer, or causing other instability issues, due to the queue not randomly dropping people
d. A little bit out of multiple options lol, maybe some of what said is true but there are other issues too.
End of day it is certainly disheartening and annoying to wait in a long line and get kicked out, feeling like you have to nurse the queue and can't walk away else hours will be lost, but even if you nurse the queue you have a chance all is for naught if you get the error too many times and it forgets your place in line. I've been lucky and rarely get the issue, am thankful for that - I have been able to play fairly consistently. I feel for those who haven been unlucky.
Seems like blizzard is doing worse and worse, can we have their servers now? Lol XD
*Worse on less not as in SE's situation with popular game not enough servers, I mean much worse internet quality connecting to do activities. Often games, programs, whatever, can save themselves from a full hard crash. If the internet did fail to pass information back to the servers, why couldn't it attempt to repair that relationship? And if it does already... shouldn't it be possible to make it try harder? lol. I don't envy situation or those having to working on this right now though, best options seem not possible (can't easily buy more hardware) and the other solutions are probably dangerous enough you don't want to just whip them out without making sure they wont cause other catastrophic issues (like if you followed New World unfortunately a few quick fix solutions to issues created much larger problems later).
