None, I’m unemployed and don’t have the money to spare :3

When I still had my last job I would donate really any time I thought about it, around 5-10$ a time. Still not really enough, but it was part time minimum wage.

Thing is they didn’t actually open-source it, as stated in other comments. They just released the api documentation. While, yes, it is a step in the correct direction, it is definitely not open-source. Open source would be releasing the source code for all the software involved, which they haven’t done.

Yeah, I have. This set of Mediatek wireless adapters don’t have any support yet despite being out for quite a while. I can’t remember what model it is specifically, will edit the post with that when I get home.
