There is a misperception about what Favre said during his Fox interview. People on this and other forums are claiming that Favre was playing GM, trying to tell Thompson who to sign, etc., and lambasting Favre for thinking he should have input on management decisions. The actual interview and the full transcript make it clear that is not what happened, and that is not Favre's complaint.
Favre did not demand that the Packers resign Wahle and Rivera. According to the quotes, Thompson was lobbying Favre to come back. Favre told Thompson it would help if he would resign his linemen. Pretty predictable request coming from a quarterback. Favre said Thompson told him he would sign at least one of them. Thompson did not do it. Favre thinks Thompson was not honest with him.
Favre did not demand that Thompson hire Mariucci to be the coach. According to the quotes, Favre simply asked Thompson to interview Mariucci. Thompson responded that he heard Mooch no longer wanted to coach. Favre told him Mooch would be interested. Thompson told Favre he would interview him. Favre hears McCarthy has been hired, and asks Mooch what went wrong in the interview. Mooch told Favre there never was an interview. Again, Favre thinks Thompson was not honest with him.
Favre did not demand that Thompson acquire Randy Moss. The Packers were interested in Moss, and Favre either was asked or volunteered to help lobby the wide receiver. Favre did that. He talked to Randy. He offered to make concessions with his own salary. He thought he had worked it out so that the deal was there to be made. Thompson did not complete the deal. He then denied that Favre had been lobbying Moss at the same time that Tom Brady was getting a lot of the credit for Moss going to the Patriots, due to one phone call Brady put in. Again, Favre thought Thompson was not being honest.
This is not about Thompson not doing what Favre wants. It is about Thompson telling Favre one thing, doing another, and not keeping Favre in the loop.
As GM, Thompson owes no obligation to Favre to take his input, or to listen to what Favre has to say about personnel/management decisions. But once Thompson told Favre he was going to do something, the dynamics changed. At that point, Thompson has a duty to carry through, or at least try to carry through, on his promise and to communicate with Favre if something goes wrong.
Many people on this forum have asked why the two of them don't sit down and talk face to face. The answer, apparently from Favre's side, is that it would not matter because he does not trust Thompson to follow through on what he says.
Also keep in mind Thompson's strange behavior regarding the retirement. He does not communicate with Favre, whereas he did in years past. Once Favre gives his retirement speech, the Packers quickly announce that the retirement ceremony will be the first game of the following season. That struck me, and everyone else, as being weird. Reporters throughout the country commented on the story, saying it is as if the Packers wanted to make sure Favre stayed retired. (Remember, they did not retire Reggie White's number until, sadly, he had passed away.) It is always better to wait a few years to do something like that. Then Thompson tells Favre he wants to cut his locker out and give it to Favre. Not put it in the Packers Hall of Fame. Or donate it to the Pro Football Hall of Fame. Just send it to Favre. On the one hand, seems like a classy gesture. On the other hand, could be perceived as a further move to "move on."
Favre apparently believes Thompson has not been honest with him. Favre told Greta that that is why he is hesitant to report to training camp for the Packers, or to even ask Thompson to trade him, because he cannot trust Thompson. He has asked for his release so that he is no longer under Thompson's control.
I am not writing this to take a side. But merely to point out how things look from Favre's perspective. This helps explain "why this is happening."
