Is writing software that has, as its default, the musical system you're familiar with, really "colonization"?
Reaper (https://www.reaper.fm/) can handle microtuning: https://en.xen.wiki/w/DAWs
A basic internet search would have resolved their issues. But why let the facts get in the way of the story, right?
I hate how these stories are framed. „Decolonizing“? „Biased“? „Hegemony“?
Screw that! If you don't like „Western“ software, written by „Westerners“, go write your own! They made the effort to design and code that software, to scratch their own itch. There's nothing stopping you! Your imaginary antagonists even created the tools for you to do so. Are you going to start complaining that Open Source doesn't understand your culture because the ReadMe isn't in your native language?
I'm all for celebrating other tuning and composition systems, but stop griping that things aren't done your way. Do it yourself!
