What about the ones that say "You must do one of these", giving a

That's fine, as long as one of the options is free. We have a very
well-known and accepted license like that, the GNU GPL.
Look at Section 3 (if I remember correctly) of the GPL. You can
distribute source along with the binary, give an offer in writing valid
for three years, or (non-commercial only) pass along an offer received
elsewhere.
OTOH, this would not be free:
You may distribute modified versions, provided that you
a) Sacrifice a cow to the deity apt;
b) Send the original author a postcard; or
c) Send Anthony DeRobertis a box of "Nerds" candy.
That would not be free because neither a, b, nor c are free. If we
added in "d) Clearly indicate your modifications" to that list, it'd
become free because (d) would be free.
Hope that helps.
