Oh really, you should recheck their license again here.
NOw, I assume you are too busy to read the license so here is why Aseprite is bad idea according to the license:
- NOT OPEN SOURCE!!!! They said, you are not allowed to reverse engineer the sofware except something something applicable by law. Even there is no presence of any open source licenses like GNU GPL or MIT. what MIT you see is the license for the some of the other modules Aseprite use. Another one, is that Yes, you can compile yourself the GitHub project, but if you make mods, YOU CAN ONLY USE IT FOR PERSONAL USE i.e., NO PUBLIC EDITS ALLOWED a.k.a. PROPRIETARY. ugh, how do I say this? yeah, like that.
- Ironic! this .org domain doesn't make sense because this aseprite is not truly open source and share the binary for costly. despite of self compilation you can do, it's just, why though?! many people doesn't like to compile manually, and want to get it ready! OH and also, they are not non-profit spirit as the org should implies.
- You want free binary? nah nah! it's old version! what' the point?!
- there are many ways to animate pixelated raster environments out there that I beg anyone to find with the only terms are: tools involved must be an open source licensed project and binary made are $0 forever, full out of the box!
So please watch your mouth before saying this tool is open source. look out their license!
Just because it is on e.g. GitHub, doesn't mean it guarantees Gratis, Open Source, and FULL VERSION spirit! some projects are pretty much (pardon my dirty mouth)... can-cer.
Cancer.
I hope you understand, that people can benefit the availability while forget and even refuse to take care for the people.
moral is, don't just care for yourself but the others as well.
