I am sticking around for the time being. While it is a community project, Red Hat is still the legal entity representing it and is a sponsor of the Fedora Project. I am confident that Fedora will continue to exist (or if RedHat ruins it, the community would fork it), consequently I feel that this is more a question of morals / ethics or desire to distance oneself from Red Hat products. With switching you would likely be giving up either KDE or immutability, until OpenSUSE's Kalpa matures more. Regardless, I'm not sure how much benefit Red Hat gets from you being a Fedora user. Unless you contribute to the project itself or are using Fedora as a means to gain more knowledge for using RHEL products in enterprise.
Some relevant articles for people interested; Fedora Project Wikipedia governance section, Fedora Project Wiki regarding the proposed "Foundation" and the mailing list discussing the "Foundation".
