Speaking only for text, you'd have an ethical (and, quite possibly, a legal)
obligation to leave the quotation as-is; otherwise you're saying someone said
something they did not.
That's distinct from coypright, though, which allows for fair use *but* each person
has to determine whether they have the right to fair use; it's not a blanket license.
E.g. I as an educator in school may pass the "fair use" test to show a film in
class for free, whereas Joe Moneybags, who wants to show the same film for $10 in a
theater without working out a deal with Paramount, would not.
IANAL,
