I can't imagine donations working that way for any organization unless you're donating a considerable sum. Every organization has its own priorities and donations help them meet those priorities. If you have a cool million lying around it might help to convince them to make Windows support a priority, but if not, then all you can do is to donate in hopes of helping them focus on knocking out priorities so that they can get to your pet issue sooner.

True in that small individual donations are unlikely to fund it. Sponsoring a feature is a thing in open source. Either through a bounty site or a fund me site.

While bounty has been existed for long time, why its taking slowly?

Maybe there just isn't much interest in windows support?

Crystal is a fantastic language for server-side programming where it pairs the performance of Golang with the expressiveness of Ruby.

I imagine most Crystal users love it for exactly that reason and have little interest in development resources being diverted to a platform that they have no use for.
