Because likely some idiot at TSC told a potential customer exactly that.
Don't ever ask those folks about caring for sick or injured poultry, they may sell all of the things needed to take care of the job, but haven't clue one about much of anything. You might as well ask the wall, the information received by doing so will at least cause no harm.

I don't know about your TSC, but around here they are very knowlegable. That might make the difference from city to backwood towns. Just saying they are not all bad. There is always idiots no matter where you go. I had a dealer tell me that when I was looking at pellet stoves. Yes, I did call the manufacture to let them know what one of their reps are saying. When you see these idiots at TSC you need to report them to their manager. Help eliminate dumb people. That is all I have to rant about..

It depends upon the output and efficiency of the stove. TallCorn vents a 50,000 BTU stove using PVC: http://forum.iburncorn.com/viewtopic.php?t=7967&highlight=pvc+abs .
ABS has somewhat higher melting point than PVC. Other plastics have yet a higher melting point...
... although some, such as PVDF, can be quite expensive.
There's probably also the issue of speed of exhaust flow to prevent condensation (212 degF) when operating at temperatures below the melting point of PVC.
It is almost certainly not to Code nor within the tolerance of most insurers, but it can be successful, depending upon the application.

That was a great pic, Bart. Like I said, success depends upon the application. TallCorn uses PVC at the termination, where the exhaust is coolest. Higher upstream, he'd prob'ly see the same drama as you saw.
Corn exhaust is corrosive and nasty at the vent termination, hence the temptation to use plastic there.
There's minimal incentive to do so for pellet stoves.

Here is TallCorn's termination after the best of 1 heating season. You'll note that the store sticker is still on it.

I just used 25 cardboard toilet paper rolls to vent my stove.
Is that going to be a problem down the road?

you know, no where in the manual, or in at the stove shops, have I seen them address the issue of back venting being a potential problem. But just look at that bent pipe! When you have so many people telling you that PVC is OK on the the far ends, and others telling you that OAK has "debatable value" (in fact one installer telling them not needed because he doesn't want to listen to them complain about cold air coming in when the stove isn't in use), then there is the issue of limited access to venting material, you can understand why there is so much misinformation being given out concerning the use of PVC for venting. I was grateful for the many good and honest postings on this forum that warned me against using PVC. Now I understand.
I went two years without OAK. I was discouraged to do this by my installer. I now have it installed and am impressed with the results. I tell others to think of it this way. Would you run your bathroom ceiling exhaust 24/7. That is the same effect you have when you don't use OAK. Venting $$$ heated room air outside with an exhaust fan. Duh!

Nope, my pallets are compressed into little pallet pellets. They do tend to be heavy though which is why I use block and tackle to load the hopper.
Seriously folks plastics should be kept out of biomass burning device venting systems, just too many things can go wrong and most of them can kill you.
Remember only you can prevent stupid burning practices.
I once dealt with a metal recycling plant in NY state that had a real "pallet" stove. The owner took a huge steel tank and stood it on its end and built it into a giant wood stove to heat his entire metals sorting building. The stove door was big enough to allow the forklift to dump a stack of whole pallets into the firebox. Now thats a "pallet" stove 
(no PVC piping though)
(no PVC piping though)I think some people are not understanding when(pvc) is being recommended.It's for the fresh air take not the venting.Venting the fire box requires dual wall medal pipe.
