People who use Linux are like people who code HTML by hand.
I don't know if you're still being facetious, but that is without doubt one of the most ridiculous statements I've ever heard. People who use Linux are simply people who prefer to get work done, without the operating system getting in their way, or automatically rebooting their PC after an "automatic update", because you stepped out of the apartment for a few minutes to pick up some groceries. Linux is the OS for people who simply want technology that works and stays out of your way, not interrupting you every 5 minutes, because it can't decide on its own whether it should let "CreditCardThief.exe" access your address book, or let "KeyLogger.exe" connect to the Internet. They are the kind of people who obsess over MD5 hashes of files they download even though internet protocols have built in error correction.
Being sarcastic doesn't really work from a point of ignorance. The reason you check MD5 hashes (or even better, SHA-1 hashes or GPG signitures) , isn't to ensure the file was transfered correctly, but that it wasn't maliciously modified, by say a man in the middle, trojan injection. But BRL should ask themselves how many users are actually using BlitzMax on GNU/Linux and how many would be using BlitzMax for a mobile platform, if it were available?
There is one significant difference between a mobile phone and GNU/Linux. Only one of them is a viable development platform. The iPhone, as fancy as it is, with it's full size virtual keyboard thingy, would still be utterly horrible to develop ON. And if they really had to make an either/or decision, which one would make more economic sense for BRL to develop and support?
From what I can tell, the Linux version costs next to (if not) nothing to support. If it was a matter of support cost, it would make most sense to drop the Windows version. Linux support could cost 50% more time for support, while the market is <10%.
Except Linux users are traditionally self-reliant, so the actual support cost is likely closer to 0%. So essentially, Linux is a license to print money. Yay!
