This is a non-issue, as it does not affect our work, only BRL's sales. If you can come up with an example of this affecting your work without it being a pointless "but if they don't market it, they won't get money to improve the product I'm already using, and if the product I'm already using doesn't improve, I won't be able to finish my work" argument, then you may have something. Haven't seen anything of the sort lately, so I'm doubtful any good reason exists for this affecting anyone's work.
The problem is that BlitzMax exists in a world completely cut off from mainstream programming. It's been around for a while, but there are still no books on programming with BlitzMax, popular libraries don't offer BlitzMax modules on their sites, and none of this will ever happen. So it's a developmental dead end, and will never be taken seriously or even noticed, even though BMX and its associated libraries are far better than a lot of other languages out there.
