Normally I'm nice enough not to spew insults at least, but the last two posts are *****ic: Fraking doesn't make a damn difference if he has force rotation on or not. It doesn't matter if two rotation-supporting apps are able to rotate, or if all of them are able to rotate. The ones that are rotating are affected by what he's talking about, regardless of whether or not their rotation is forced. (And even without forced rotate, CSSU enables 'actual' rotation support in the settings menu, modest, and will do so with other programs as it replaces the closed bits with FOSS ones.)
This is ridiculously frustrating, and don't start with "it's not hard to avoid" and "it's never happened to me" because with especially with the CSSU, portrait is almost everywhere, and there really should be an easily accessible way to set the "rotate-ability".
