This could be coincidence, an very badly timed coincidence, but a coincidence none the less, you can make up your own mind.
Short version of a long story: Original Claptrap voice actor, David Eddings, has got beef with Gearbox CEO Randy Pitchford. Insults and accusations have been flying around, David saying they wouldn’t pay him the going rate to return as Claptrap, Randy saying they made “a relatively generous offer to reprise the role,” but David declined the offer. Then there was some stuff about assault, Pitchford calling Eddings “bitter and disgruntled” for being fired, it all got very messy.
Gearbox then announced new DLC for Borderlands 2, a new episode bridging the second and forthcoming third instalment of the game. The DLC includes a mission called “Claptocurrency” in which Claptrap tries to amass a fortune via nefarious means and backstabbing. Of course, this goes horribly wrong….and then this happens.
As I said, could just be a coincidence.
