We all need to keep in mind some parameters (yes I read the thread you linked to)....
Foremost, it's a mechanical apparatus comprised of many parts and being a mechanical apparatus, you will have a failure rate in the field, thats a given. How many cars go back for warranty fixes for instance. A recent example comes to mind. Chrysler literally sold millions of Jeeps that are prone to fires if hit in the rear and now that have to fix the issue or the Ford cruise module fires on diesel trucks, Ford is replacing the module... Parts and assemblies fail
Vortex stands behind their product with an unconditional lifetime guarantee (just like all reputable scope manufacturers do, so, IMO, an issue is no issue because it gets fixed or replaced, no questions asked.
I have 3 Vortex Vipers, one on a 338 Lapua. No issues. On the other hand I have a very high end Leupold (like twice the price of a PST) thats on my bench rest target rifle that had to go back to Leupold and Stevens twice, one time for a reticle shift and once for a parallelax issue adjustment issue. Both times Leupold and Stevens paid the ship costs both ways and did a quick turnaround, exactly the same service you'll get from Vortex optics,
if the warranty service need arises.
Don't worry, if your porridge is cold, you can reheat it.
What I'm alluding to here is the issues, real or imagined are, in fact, no issue at all.
Far as I'm concerned, their glass is good (enough for me) and I don't dwell on what could be an issue until it becomes an issue.
I'm not a rabid
fan of any optic. The prices to value ratio of Vortex optics makes them very attractive to me, and, obviously many others...
