Proven on which other forums? The 'Official Gateway Support' forum over at Max Console? Sure, because GaryOPA (the administrator there) is going to be completely unbiased given his involvement with Gateway.
This happens in almost every industry, somebody will create a product and others will rip it off. How often do we see companies taking it out on the consumers? That's not good for anyone.
You'd do exactly the same? You'd intentionally write code that can cause damage to the hardware, and then distribute it to even your own competitors in the hope that your code is solid enough that it will never affect them? The R4i Gold team aren't going anywhere and the Gateway team aren't going to get rid of them by bricking consumer devices.
Gateway isn't distributing anything to their "competitors". Competitors are decompiling laucher of Gateway, steal all code from it, don't analyze code at all, just patching so it works on their shitty card and distributing to thier users. R4 users have faith that what they download from R4 site is safe but it isn't, because of incompetence and idiocy of R4 team.
