299 is, indeed, inaccessible for many people. But, the devs live in places where things cost more, so its also a tiny price compared to the relative value that they provide.
I do think that some sort of geo-relative pricing structure would be worth looking into, but how does one even implement something like that? Is there something that makes it all "just work"? I suspect not. Moreover, the devs have already given away so much of their time - it doesnt make much sense for them to invest even more of it into designing a pricing system like this, from which they are going to possibly earn only a negligible amount from. Perhaps this is a problem that you might like to address yourself?
Anyway, the devs are very clear that most people should never need the Pro license. 95+% of the functionality and value is available for free in the open-source library. Use it, enjoy it, learn from it, profit from it!
