Well, it is still open after all, given you are a very experienced guy you should consider rolling the sleeves and sending some patches to fix that, right?
Giving back to the community for something you get for _free_ is nice.
My gratis work is done for things that really matter to fellow humans, like charity, poor people on the street and not so lucky people that need an helping hand to get back into society, refugees that almost faced death running away from oppressive regimes.
That is where I can gladly give my skills and money.
Look buddy, your experience (having a bad time) with Linux seems to be quite frustrating, I couldn't find one positive comment about Linux from you in this post.
Maybe I'm very lucky with Linux, but I don't agree that it is as bad as you are saying.
I'm sorry for you, maybe you should stay with windows indeed. :/
