if what Health claimed isn’t a violation of Af Atem B’chinam, then nothing is.
First of all, I think its pretty obvious that Health was not actually expecting any payment here. That statement was just part of his general bluster. (As was the case in http://www.theyeshivaworld.com/coffeeroom/topic/is-zionism-the-yetzer-hora/page/6#post-607909)
But anyway, even if he would have been serious, I don’t see why the heterim that apply to paying Rebbeim (sechar battalah, chiddushei sofrim, etc) wouldn’t apply here.
