With respect, that's not what you said. Your point was that if Google offered paid for services then commercial sites would have an advantage and that would mean poorer search results for users. The implication is clear: More commercial sites at the top of SERPs is bad for the user. Info sites shd rule! :)
If Google offered paid for services those commercial sites that are of genuine top quality but are languishing in the SERPs can sort their internal problems out to compete properly, rise to the top in SERPs, and provide a better user experience.
What have you got against Google SERPs improving?
