I agree with the proposal and I think it is a good idea to get paid for hacks. It might motivate some people to write more

I also don't think that allowing that will adversely affect free hacks, just look at the strength of OS software these days...
The other thing is people already have links in their sig to their businesses, script providers, style makers etc. If this proposal doesn't go through, will the rules change and no commercial links be allowed at all?
