Hannity doesn’t need Fox News any longer. He has other options.
If Hannity would suddenly find himself employed by a proposed EIB-TV network, and was aired at 8pm EST during Bill O'Whatshisname, I would watch Hannity and I am sure that a whole lot of others would too!
Bottom line is you are right. FOX needs Hannity a whole lot more than Hannity needs FOX - and he ought to push the issue.
