As the person who kept pushing the ADS hypothesis, shouldn't someone at least
try to confirm whether or not that feature is being used before assuming that
it's actually the source of the problem?

The reasons for my believing that ADS had something to do with the problem
were, from my perspective:
1. Very few, if any, Wine users were having success running the game without
bypassing its protection mechanisms. Many were having success after the bypass.
2. Very many (and perhaps all) native Windows users who had installed Steam and
their games onto FAT-type filesystems were having similar problems.
3. Even though the API isn't portable, filesystem forks exist on both
Windows/NTFS and Mac OS X/HFS+, and I couldn't think of any other
userspace-exposed, filesystem-dependent feature that I didn't think was
supported in Wine. Furthermore, if ever one wanted to have data that stayed
with a file in an obscured way but wouldn't easily leave the machine on which
the file originated, something which matches the M.O. of DRM, forks are a good
way to go.
4. Valve was brick-walling even clearly legitimate customers on supported
platforms. They were suggesting conversion of filesystem to NTFS as a
work-around. Use of FAT filesystems is also plausibly something that could be
overlooked in the design and testing of a DRM system---because, I mean, really,
who uses those things anyway? ;)

Evidence against that hypothesis was:
1. Even some NTFS users were having similar or the same issues. (These could
have been other issues, though.)
2. No one had come forward saying that ADSs were even being used, something
which could be extrememly easy to confirm, depending on how this feature was
being used if it were.

I would confirm it myself, but that's difficult without a copy of Windows
(which I don't have) and a working copy of the game. Plus, I didn't get much
interest from users in Valve's own forums. (I figured that I might as well vent
along with everybody else at the same time as I sought productive answers.) :D
