I have been a Veritas customer for over a decade and I do not consider its leaving a product on its website that it has every intention to manufacture again anything wrong. Neither is it misleading nor is it deceitful by any definition. Many supply factors are outside the control of a manufacturer and when a company is sure that there is no hope that a product can be reproduced again, it will then make the market decision not to make it and withdraw it from its catalog. Simple business practice and there is no need to make any conspiracy theory about it.
On the other hand, a company that says certain of its products are one-time only but then reproduces and sells them again (and again) due to customer requests, in my view, fits the bill of being misleading. I have found two such examples from two different vendors recently.
