They said "... in the future, should College Board be willing to come back to the table with lawful, historically accurate content, FDOE will always be willing to reopen the discussion" and that makes me think they intend to dispute some content (which they may very well not though it is the only thing they seem to cite). Would have been nice to hear what exactly that was.

Honestly... since they didn't say, my bet is it's something unflattering that is likely true.

I dunno, you can openly view curriculum for virtually every AP course in the country - except this specific class. 

If College Board is unwilling to publish the curriculum like they do for their other courses it’s because even they know it’s bullshit.
