Personally I don’t think it’s mixed

As someone who (outside of basic game modding) hates to tinker out of fear of breaking something, that second part is aimed at people like me.

In other words I read this is “Hey FlipFlop, you could make all these changes, but let’s leave that to your buddies who actually know electronics and hardware so you don’t end up with $100 steam brand paperweight “

Edit: check out the page and that’s pretty much what was said right after “Any damage you do will not be covered by your warranty” “You might break your controller”
