I think at some point it would turn Wikipedia into a huge advertisement. You'd have every person who ever came up with a product create an article about how theirs does all these great things and is better than the others. If you've ever taken a look at the recently created articles list (http://en.wikipedia.org/wiki/Special:NewPages http://en.wikipedia.org/wiki/Special:NewPages) you can see examples of this. People copy-paste text from press releases (which violates Wiki's policy on copyright because all articles are technically released under CC-BY-SA) and write text that's really heavily on the advertisements. And I think that there really needs to be some threshold in place, if only to keep that stuff at bay.
