reintroduced the "proprietary open source" expression again. 

 So I did a little bit of research.  He created a page with the expression "proprietary open source" on November 20, an expression which is not only an oxymoron, but is intended to hurt Mono's image by adding a negative connocation to it.   The sole purpose of the page was to associate it with Mono, as can be seen by the fact that the only two pages that linked to it (up to January 19th 2006) were the Mono page and the .NET page when referencing Mono. 

 The IP for 83.237.108.102 and 85.140.83.108 belong to the same person, he goes by the nickname "krokas" on irc (this can be found by googling for his ip addresses) and he is involved in the development of a competing project (dotgnu).   Krokas has used the expression "proprietary open source" a number of times on their irc channel.   The only other mention of the term "proprietary open source" on the web has a different connotation and was used by Bruce Perens when refering to the subscription and support models that are provided to customers purchasing the software (and is in no way related to the actual contents of the actual page Mr Krokas created). 

 This practice Mr Krokas dislikes so much is often refered as Dual license, and the Wikipedia article on the subject is not politicized by the desire to promote one project over another. 

 Other projects that have commercial backing and require copyright assignment have not received the continuous flood of edits from Mr Krokas: OpenOffice, MySQL, Qt, Berkeley DB and other projects that use dual licensing to fund the open source development (The page Dual license has more projects).
