This could be everything or it could be nothing. Oftentimes athletes will change up and clean out their social media to reset themselves for a new season. In this case though with all of the turmoil between both sides, there is likely something more.
With the continued drama between the two sides, a trade for Carter Hart feels more and more likely. Hart is still just 25 years old which is young for a goaltender. He likely still has value to several teams around the league. One factor might be holding up a potential trade though.
Carter Hart was a member of the 2018 Canadian World Junior Team. With the current investigations going on with that team and their scandal, this may be impacting a potential trade. Once the details of who was involved are released this situation might be able to progress. For now, Hart, the Flyers, and other interested teams are in a wait-and-see period.
