Developers aren't "abandoning" the Mac platform so much as they're re-focusing on areas where they'll be more profitable (i.e., less freeware/open source development and more towards areas such as iPhone apps).
If anything, I'd imagine that Apple software development is at its highest in years overall, given the increases in marketshare that Apple has been experiencing.
I said that it makes sense to me as to why they'd do it: why put in dozens, hundreds or thousands of hours of development time into a project that provides no financial return when you can spend that time working on an app or apps that will provide financial return?
No where did I say that I thought it was a good thing. Understanding a reason =/= thinking it's a good thing.
Edit - I should add that when I mentioned that I knew only a few Mac developers, that's how it's been for years. They're still developing for Mac, and I even know a few people who started off with Windows and eventually switched. It's just when Windows (between its various versions) is at 93ish % of the market, obviously a large portion of your developer base will be developing for Windows, because that's where they're likely to make the most profit.
And nowhere in my post did I say you thought it was a "good thing", I said you seem to be just fine with the fact that they are abandoning the Mac platform. Your words about them focusing on areas that are more profitable is the same thing as "abandoning". What do you call it when developers put their focus towards where the money is, and stop on areas that don't? A vacation? NO. I call it abandonment.
My point was, if this was really the case that it was just about money, I find it hard to believe the Windows customers are really offering much in donations for VLC. There's more behind it.
