Lets not forget that 3DRealms (the old 3DR) was always quick as hell to shut down any fan made project based on Duke.
Any mods to recreate Duke in newer engines were shut down almost instantly. 3DR (George and Scott) were always incredibly protective of the IP, and all their IPs.

Yet, now that Gearbox has control of the Duke IP... and the Anthology is being removed, GBX has now become satan almost. And, there's nothing even confirmed about this being the reason why.
There's nothing about The Megaton Edition being removed, GBX has no part in that. Nothing about the Platformer pack with DN1, 2 and Manhattan... and they aren't going anywhere.

Sorry, but neither Fred or 3DR have said why it's being removed.
And, blaming Gearbox is an unsubstantiated rumor at this point. The deal between 3DR and GBX could be a reason, it could not. We don't know. And until a statement is made, we won't know.
So it's pointless to blindly point a finger and be like, "It's their fault!!". That doesn't do anyone any good in this industry.

I like Gearbox. I love the Brothers in Arms series, their Half-Life expansions were awesome, and Borderlands 1 and 2 are great. Yes, A:CM was a disappointment, and the way SEGA (yes, SEGA, if you believe GBX was able to make decisions such as the ones made about a game they didn't even own without the approval of the owners...) and GBX handled it was disappointing.

But, one flawed release is not enough to overshadow all the great games they've given. If one game was all it took... I'd be hard pressed to find more then one developed I'd be able to still follow.
