Most of these are created and maintained by people who are just like you and me and care about freedom and privacy. I think open source projects really reflects the “humanity” aspect of human civilization, it sounds a bit odd, but when you think about it, there is very less incentive for normal people to contribute to the open source. It is the frustration from dark patterns that give people some motivation to support and contribute to open source. This is atleast how I see it and why I so strongly support the FOSS cause, other people may view it differently but to me it reflects on humanity.
