There’s a difference between liking someone (which doesn’t really matter) and trusting their judgement (which is what I think folks mean here). I feel it’s somewhat important for the later to be true, especially with security related software.
Is there evidence that this generally leads to more security vulnerabilities? Is there evidence that specifically in WG, Jason's (technical) judgement has been flawed?
(I think the answer is "no" in both cases. Disclaimer: my company also donated to WG development, specifically to get cross-platform support :))
