I think you're generalizing from your position inside some bubble, I am not sure which. Equivalently I could imagine game developers generalizing that linux people are terminal fetishists and have no interest in getting stuff done, who would rather customize (a.k.a fight) their OS for days on end than provide end user value, and through their idealistic, puristic and dogmatic approach to FOSS they feel safe but are meanwhile vulnerable to exploits of bad actors through supply chain attacks.

I think neither take is true, nor does it hold much value to claim it, unless your aim is to divide developers into arbitrary adverse tribes.
