I like the idea of pledging, though there may be some variance (what if a startup violates a startup, margin is high, the technical innovation was real, etc?) That being said, there is a lot to be said in simplicity.
I'm no lawyer - I have to ask the logical question - does publicly stating this pledge bust any opportunity to double back (i.e. it is more legally binding than just a pledge?)
