If this is true, runDisney will have a terrible month PR-wise.
Even besides from discussing if these are valid reasons to cancel all West Coast races including the three challenges (C2C, C2C pink & Kessel Run), it will be a tremendous impact on runDisney: both financially but more important; their PR.
runDisney itself cannot be blaimed for these constructions. However, they can be blaimed for their terrible communication surrounding it. The projects have been known for quite a while, and I'm very interested how they will coop with the aftermath of such a announcement.
So, again if this is true, we have the cancelling of the races itself, combined with runDisney's (lack of) communication, filled up with insecurities surrounding legacy status & compensations for Light Side, and to top it off people who might wanna cancel their WDW races when there are no C2C challenges possible.
I'll get some popcorn and have my social media feeds ready for a lot of people willing to lynch some runDisney webcare people.
Edit: announcing it this week would be before the W&D + Avengers weekends. Not only their social media will have angry mobs ...
