I'm pretty sure I saw the post that was removed leading to this thread. I think in a thread started about multiple brands, it probably would have been left alone. In the thread in question though the OP was just sharing his new purchase and asking for advice. That's not really the place for brand vs. brand stuff, even if it's just a harmless joke. The post was removed to keep the thread on topic, big deal.
I've had posts edited by mods before, and they gave a valid reason for it, and I moved on. It's an internet forum, it's not that big of a deal if your post gets deleted!
Be glad the forum, which you clearly enjoy, is provided free of charge and isn't nearly as much of a mess as many other boards. There are plenty of places on the internet that don't have rules to follow, so I can deal with a few here.
