In VZW's defense it was not their decision to not run OS6 on our S2's. The blame here goes to RIM and their not being able to see into the future enough to have beefed up the memory and processor to today's standards. If it is true that VZW tested OS6 on the S2 and then discontinued it they had a good reason. I would guess the device did so poorly that it would not be a wise business decision to release junk.
On the other side of the coin, VZW could have insisted that RIM include at least 512MB of RAM instead of the 256. After seeing S1 units fail because of low memory due to OS5 being huge and then adding applications. If the S2 refresh rumor is true it should be offered to S2 owners at a very good price with no contract extension required as an act of good faith. Lets face it, the unit if it does exist will probably be a refurb anyway and they will take the trades add memory and resell in the same manner. Personally, I will not go for the refresh. I'm waiting to see the S3 before I make any decisions on leaving the BlackBerry platform that I am very comfortable with.
So I hold both companies at fault not putting the customer first.
