What possible reason could one have for differentiating 2 files on nothing but case?

1) Programmer copies files from linux box to windows box of a certain age.
2) Programmer makes some changes in windows land.
3) Windows loses the case of the filenames
4) Programmer copies files back to the same directory in linux land. Now there are two different files README and Readme.

You mean OFDM? Try googling "who invented OFDM". It dates back to the 60s.
I am one of the authors of 802.11 and 802.16 that both use OFDM. So are many other Slashdot readers.

I'd prefer for everyone to pirate it.

You screw the North Koreans (and their supporters) and Sony in one go. Win Win.

And ironically, it seems that will be the only way to watch the movie for the time being. Cause the terrorists have won.

So when the terrorists win, so does free speech?

Bingo. You have won the internets.

An algorithm changes its behavior based on the value.

The example I gave is a sneaky algorithm in the FIPS spec that deletes consecutive values when they match.
I.E.
If this_value == last_value:
    don't output this_value
else
    do output this_value.

This is on the output of an RNG and so it reduces the entropy in the random numbers because there are no matching consecutive numbers, whereas in a full entropy stream, all pairs would be equally likely.

In the context of noise in statistical analysis, it can confound the additive noise models.

Algorithms that do things to data, but don't look at the values of the data when deciding what to do are not data dependent and so that limits the scope various bad things to happen.
