There are also quite shady SEO tactics where webmasters get asked to remove links by unrelated entities.
There is a danger that good sources for linking will be frightened into either removing links, or no longer accepting them. Folks read and the subject is viral.
That's not what Google really wants either, but the definition of "paid" can be so gray at times it's not worth playing with.
One positive thing will be link equity will rise amongst the precious few, so Page Rank will probably make a comeback with the "jolly green bar" as a redeeming ranking factor again.
