I don't think for profit people are scumbags. The deal with these blogs is that they exchange information for money. The money aspect is optional, without paid subscribers. IF the post is too helpful it might not garner money, if it is too biased towards just making money it may not be too helpful to those with knowledge. Its a balancing act.

People are getting a little ahead of themselves with the high and might moral code here.

The only Scumbags I have met recently are working for non-profits, now that is a different situation altogether.
