Because of limited developers working on arm windows in my team even in China, the development progress is less than satisfactory.<snip>

... your statement is precisely my point.  If your project were 'open' available on git, then you would have the 'world' of developers helping you from every continent.  You become a re-seller of pine(s), and your code becomes better and comes to market quicker as your value-add because you're not working in a vacuum. Isolationism and protectionism do not work.  In the 21st century the 1980 business model of IBM will fail rapidly.
