Understandable to believe that they should be getting updates (I have gotten updates like this from Shapeways, Amazon and many other retailers over the years). To play devil's advocate, though, we don't know how their merchant software is written, the access they have to the customer/order records, if they actually control that information, or if it is even possible to get that for a bulk mailing of selected software. May be something that would cost more than they can spare at the moment, may be something that will take time to implement, may be something that is a strictly manual process. Working for a major corporation, I have tools available for mass emails, and can get mailing lists from various applications, but a smaller company may not have these luxuries.
with the crunch that is going on now (larger than expected order volume, supply chain delays, holiday rush) now is NOT the time where they can afford to take the risk of any changes to their systems. Or devote a number of individuals and man hours to personalize communications. I would imagine that all resources are in a "all hands on deck" scenario, and any extra cash flow is funding temps to assist. If that is the case, then I would say: "You see the delay mentioned on the website, you know about the mass communication through Facebook, so you know why, what is going on, and you are informed, and VS is offering something to help make it right with you... So now I ask: do you still need a personal email sent to you, or would you like your device a day or so sooner?"
Even ProtoVapor is going through the same pains, but with them being a US company and producing a much smaller quantity, it may not be as pronounced, but between their 5-9 business day lead time + 4-5 business day shipping delay, you are looking at 2-3 weeks (14-21 calendar days) plus actual shipping time in addition to actual transit times to get a device... vS isn't that much behind them there
