Being upset isn't the issue.
This place thrives off of discussion and truthfully there is always very little over the summer. The direction of the team is largely decided already in keeping the big 4 - so the next 4 months will just be bickering on whether or not that was the right call with name calling and misinformation/positioning. At least previously there was more to dissect on building out the D, reasons for the playoff losses, some more substantial changes to the roster and/or direction of the team.
It is already is hostile, frustrating and just tiring to be here right now.
For those curious on what I'd do with this team - personally I'd move on from Marner at the very least, keep Dubas and Keefe for a year then reevaluate. I'd increase the speed and pace we play at, I'm not as focused on size as others.
