Having had several technical discussions with Jacob, I’m certain he’s technically skilled.

(I’m a former Google engineer, have worked on privacy and security software [I created Disconnect, have contributed to HTTPS Everywhere].)

I will second the statement that Jacob is an able and skilled developer.

I have worked with him on projects long ago, however, so he can certainly have chosen where to focus his time and attention. Just because you don't see him code, don't assume he can't (replying to Grandparent of course)

Are you meaning to imply that "activists" cannot or do not do anything productive? If so, you might want to reevaluate that belief.

You sound an awful lot like a developer that doesn't think they need a project manager and is oblivious to the chaos that surrounds them.
