Missing one important proviso: public relations workers are quite welcome to edit wikipedia in a personal capacity. What has been prohibited is editing Wikipedia on behalf of a paying client.
Again, see the case of [[Arch Coal]]. Nobody paid or received any compensation for the authorship of that article. Still, Jimmy Wales deleted it and banned the original author. These quotes from Jimmy Wales don't sound too welcoming to public relations workers, regardless of their potential desires to edit from a "personal capacity":
"I deleted the articles and banned Kellen Communications from contributing. I think that PR-firms editing in a community space is deeply unethical..."
"I think the article is a travesty of NPOV. I am glad that it is undeleted so that people can see. It is corporate fluff." (Once again, this was regarding an article about [[Arch Coal]] that the community eventually reconstituted into Wikipedia, and for which no money changed hands. Nonetheless, the user was still banned for 30 years.)
The more excuses and explanations that the community comes up with, the more obvious it is that you're avoiding the real issue. Wikipedia unilaterally has chosen to discriminate against non-volunteer activity in the article space, despite the likely fact that the credentials and income sources of 90% of editors are never questioned or verified by the community or the Wikimedia Foundation. Only those who state that they are being paid in some way are excluded. I would argue that if you looked at the original authors of the New Pages in Wikipedia, 90% had some financial or career "conflict of interest" that could be found if everyone was exposed to a background check. You'd also be interested to know that a public relations firm called Schwartz Communications created their own article in Wikipedia, and it was defended for some time by the Wikipedia community. Why? Schwartz did some amorphous pro-bono work for the Wikimedia Foundation. Talk about a conflict of interest!
People who have never purchased or sold a pet skunk are unlikely to start an article about [[Pet skunks]]. The ones who do start such articles don't seem to get questioned about their income sources, investigated, or banned, though. Seems that there's a different standard when an article is about a corporate entity. That's discrimination.
