nah, there are different ways to approach foss and different sizes and scopes for project. Primal is evidently a more "company-driven" project, and its okay, it has his role in the space. In the end they implemented nips and tend to be compatible with protocol releasing source code for every binary they ship.
Also the product is solid, more than most of the community-driven projects can be, due to more resources invested.
I also prefer to use and contribute to more community driven projects, and I think that they tend to respect more users and become better with time, even if initially they tend to be more buggy and unpolished.
But every software has his space, and primal team is definitively a good actor, delivering a fully foss client on multiple platform.

And no seriuos dev has forked and worked on main branch without realizing that the company was working on other branches, it require just a minimun literacy and competence to figure out.
