(I'm the CTO of Joyent.)

Sadly (and despite repeated pleading), Quizlet didn't bother to do anything -- at all -- with LX-branded zones. This was a bit dispiriting because they were part of the motivation for the work (namely, a customer of ours that was upfront with the "impossible" demand of the performance they saw in a SmartOS container but with their Linux stack). I think that even by the time the LX-branded zone work was clearly on a production trajectory (i.e., late 2014), they had already implicitly decided to move away from Joyent to a more established brand. That's fine, and I don't fault them for it (and I definitely appreciate their kind words for Joyent in general and our support and engineering teams in particular) -- but I do wish they'd been more upfront about their rationale.
