Fantastic to read this. I am always on the look-out for non-exploitive solutions, having avoided Google, Apple and Amazon to the best of my ability for ten years. I will be downloading and implementing Mycroft AI as soon as possible and I will support the effort if it turns out to be as good as you indicate.
As to open source quality, there are, of course, lots and lots of open source programs out there and so many will be worthless vanity projects. I don’t think you’re talking about them. I think you’re talking about the brilliant and fantastically useful open source projects like PostgreSQL, MakeMKV, Lighttp, Python, Linux and the many many others that my family use every day. the open source business model is a little hard to grok but people all over are sharing wondrous software for our benefit. We should go out of our way to support them.
