I don't want to get involved in this argument as obviously nobody's going to win it (unless someone compares the other to Hitler, of course, which automatically make him lose).
But I would say that Timberwolf downloads isn't representative at all.
For starters, anyone running OS 4.0 can't run it. Yet they're still OS 4.x users.
Secondly, anyone running a Classic is much less likely to try it, as they just don't have the horsepower or memory needed.
Thirdly, most of us are quite happy using OWB. I'd say some people may be saying "I'll download it when it's out of beta".
It's not fair to base number of owners on downloads of one program, no matter what that program is.
Back to lurking for me.

Edit: Personally, I use OS 4 mostly, but I'm pleased for MOS in the same way as I'm pleased for AOS and AROS, as succeeding at all with such a small market is something we should all be proud of, whether it be the OS we use or a different one. We're all in the same boat, here.
