Sorry, I vote against by principle due to the concept mechanism of said protection. I'm very careful about the software I install on my systems to ensure their longevity and stability which are essential to my work. Quite naturally I wouldn't trust a bit unless proven otherwise (so yes, typically I use open source software). Plus such system would be quite easy to circumvent unless it is applied as a wrapper around main executable, but at that point I'd be even further against such method.
The concept of "guilty until proven otherwise" is ridiculous.
