Firstly what we the consumer some times sees as a bad thing, I am talking about the friction, animosity, hatred etc between manufacturers is not all what it seems and is not necessarily a bad thing for the end user.
The competitiveness and fighting for market share means that the end user gets a better product at a better price with good service.
Even when new products come out and there is a bit of banter between the manufacturers, this is just part of the process that has made South African gear so good. The guys feed off each others developments and ideas and continue to try and out do each other .... like I said a good thing.
I will go as far as to say that even in cases where one manufacturer has ripped off another's product, this is not a bad thing. I know the guys get upset and rightly so, but for us users its good. Here is why, the who got ripped of is so pissed he goes and improves his original idea making it better.
Again good for us!
I think most of this 'problem' is on the consumer side .... like a bunch of mad soccer fans rooting for a team ... damn hooligans
