Are their issues really that valid?
> For example in 2012, a trustee of the Wikimedia Foundation UK used his position to place his PR client on Wikipedia's front page 17 times within a month. Wikipedia founder Jimmy Wales made extensive edits to the article about himself, removing mentions of co-founder Larry Sanger. In 2007, a prolific editor who claimed to be a graduate professor and was recruited by Wikipedia staff to the Arbitration Committee was revealed to be a 24-year-old college dropout. These are only a few examples
From their examples, it seems like the issue that spurred the development of Ibis was that a few individuals compromised a select set of articles.
They seem like nitpicks to me.
I think more motivation is needed to justify why to abandon Wikipedia. It will be no small undertaking for them to rebuild the world's largest and comprehensive knowledge repository.
