It depends on the criteria for a "bad" game development company.
If it means which company is most evil, then it's EA Games. If it's incompetence, I'd say 3d Realms considering they were so incompetent that they got sued for it.
If it's how much a company fails at sustaining their own franchise, then it's Sonic Team, because the best Sonic games in the past 7 years were NOT made by Sonic Team.
Sonic Team has a special place in the dark side of my heart because of how much they keep claiming to revive the franchise only to not only fail, but also REFUSE to listen to their fans. All fans want is a decent Sonic the Hedgehog game, but instead, they get games where you spend more time playing as other characters other than Sonic the Hedgehog (note how I say Sonic the HEDGEHOG).
