I believe you don't know what you're talking about. Forbe's thought it was an open source issue. I don't think many would say Forbe's has a radical open source "agenda". http://www.forbes.com/sites/benkepes/2015/03/25/a-cautionary...
EDIT: just to clarify, i'm not saying Forbe's said FDB is open source. i'm pointing to the fact that someone that writes for a national business magazine about open source issues thought it was an open source "issue". if persons working in open source can hope to make a living, counting business as a stakeholder is a good idea.
Are you for real? Are you telling me that a someone's blog on a business magazine has a larger knowledge of technology than someone who's actively involved in it? If you have a medical condition do you also read health industry section in Wall Street Journal?
By the way, if you did not see it there was an update posted that states that FDB was closed source. It also doesn't matter that some components were open source or not, because without FDB they are useless either way.
FoundationDB was closed source, they just allowed to use their product for free in small deployments.
