There is a confusion here. Cutter Gauthier, through his agent informed the Flyers that he would be returning to BC this coming season.This isn't accurate. Gauthier indicated he wanted to play in BC this season with the addition of the BC line to try and win a championship down there.
The contact after the Worlds in May last year over zoom was the Flyers thinking he changed his mind and wanted to go pro (the Flyers were ready to do this) - but instead it was CG saying he did not want to play for the Flyers. The argument about this year hold no water. If there was a contract argument, I could certainly see it more last year where the Flyers weren't willing to burn an ELC year in his draft + 1 year (10 games) where it might have soured. THAT makes more sense than this year.
I don't know if that's where Briere got the "list" of teams he'd play for, or if he even got a reason - that may be just media-speak.
However, those talking about "Gauthier doesn't owe them an explanation" may be valid in an instance where there is no investment made into something; i.e., no asset was spent - say, like when he's a UFA and he says "I have 0 interest in playing for the Flyers" - that's totally fine.
But professional courtesy here is that the team invested a high draft pick, in a player who stated he was willing to play and "excited" to be a Flyer - to which it cost the Flyers a high value asset that they have invested into him. To later then state "I changed my mind, and have no interest in playing for your organization" is breaking a verbal agreement, and not providing an explanation or rationale - is a violation and from a professional conduct point of view, you do owe an explanation of why you are breaking that.
Now, did he provide one or not and the Flyers are not getting the hint and still pushing? Maybe. But the comments from the agent in response saying "Drafted players are not entitled to play for the organization that drafted them" seems to imply a lack of accountability in changing his mind (which is ok to do, but when you are an investment you should provide a reason). That is actually the purpose of the draft's existence - your rights are owned by the team that drafted you - and you are beholden to play for them.
If there's an issue with that, then these agents need to fight for it in the next CBA about what the draft rights actually are.
So all in all, it just seems like CG changed is mind and is trying not to get blamed for it. It doesn't really work that way. Ghosting isn't really the right move regardless of saying yes or no - organizations, corporations and people are always persistent to see if they can rectify or fix a situation - that is a mature attitude. CG did not even give them the light of day in order to do that. It's perfectly ok for him to meet with whoever went out of their way to try one last time for him to say "thank you for coming, but I hold my position I stated previously, please trade me" - and again, I don't blame him for this as he's a kid - but it sure seems like he's gotten some poor guidance.
Good luck to him.
That report came out just before the WJC.
