Good catch!
Those logos were made by one member of BitShare's decentralized community while another one was attempting to get the trademark approved. The US government authorities declined to issue a trademark because, in their profound wisdom, the name was "too descriptive".
Apparently they thought it described a company that was in the business "sharing bits". (I'm not making this up.) No amount of reasoning by the BitShares lawyers could dynamite them out of that highly insightful position.
So, we need to circle back around and encourage all the independent decentralized users of the BitShares logo to properly reflect the current status.
A bit like herding cats, but that's the price we pay for total decentralization. Nobody can order anybody to do anything.
Gotta love it!

So, let me get this straight. You tried to trademark it and would have, if you could have convinced the USPTO, but since they denied your application, you come on here and attempt to prove your "decentralization" by advocating the fact that you're not "trademarked" when in fact you attempted to do so. Yeah, that sounds TOTALLY above board. Hahaha
You might want to get around to changing those logos "Mr. Decentralization",
it's been over THREE months since your application was rejected. I'd hate for people to get the idea that you're a company.
Of course. BitShares is a company! If the owning stakeholders think that will make them more profitable and grow faster, why can't a company decide to do that?
In the short term, while shares are worth pennies
Remember, BitShares is a company, not a currency. It is a unmanned, decentralized company that produces and trades interest-paying "smart currencies" as its product. So judge it by whether it is a good idea and implementation for a company, not a currency. Then you can get past all the accepted rules that (may or may not) apply to future currencies and see clearly what the investment opportunity truly is here.
