Celtics re-hire Darren Erman, who was fired by Golden State for secretly recording player-coach conversations

Earlier this morning Adrian Wojnarkowski sent out this tweet confirming a Celtics new hire:

In his follow up article Wojnarowski quotes Celtics GM Danny Ainge:

"Darren worked with us for four years and he was one of the hardest working, most competent and intelligent members of our organization," Ainge told Yahoo Sports. "We welcome him back." 
Before agreeing to rejoin the Celtics, Erman had job opportunities that included rejoining Doc Rivers with the Los Angeles Clippers, league sources said. 
Erman had worked as a coaching associate under Rivers with the Celtics from 2007-11. Erman also had worked closely with past top assistants Tom Thibodeau and Lawrence Frank on Rivers' staffs.

Erman was let go by the Warriors three weeks ago for a "violation of company policy."  Now here's where this story gets weird, especially in light of the Donald Sterling tape that came out over the weekend.  Also this morning, ESPN's Chris Broussard is reporting the reason for Erman's dismissal was a number of conversations which he recorded between Golden State players and coaches:

Sources said Erman, who was coach Mark Jackson's second assistant, would record coaches' meetings, meetings between the coaches and players, and informal discussions among coaches that took place in the team's coaches room -- all without the participants' knowledge. 
"He was taping everything," one source said. "Taping pregame speeches wouldn't have been that bad, but he was taping guys just sitting around talking in the coaches' office."
Sometimes Erman would be present during the tapings. Other times, he would leave the room and leave his phone behind to record conversations the other coaches were having. 
It is unclear what Erman did with the recordings. The sources weren't sure whether he shared them with the club's owners or front-office executives. "Was he taping it for himself or was he taping it for management? That's not known," a source said. "But he had a lot of communication with members of the front office."

Whatever the reason was for Erman's actions in Golden State (like with Brian Scalabrine, it appears there was friction between Erman and Jackson), Ainge and the Celtics apparently are not the least bit worried:
