Social gates, not tech ones. Linkedin exploits the network effects of gui-ninjas under stockholm syndrome to an anti-user service.

The same reason you get wierd looks when you say you don't facebook sometimes.

It's like existing outside the control or influence of some $manyuser $app/$website is unthinkable to those who exist within the prison ecosystems. I am a greybeard linux admin moonlighting in windows world, and the state of infra in ms land is baaaaadddd. When I tell engineers though, I get a thousand justifications about why its ok that its this bad (because it was worse before, etc), because the tooling is so bad it gets in the way of accomplishing your goals.

Same mentality... I personally don't really understand it. Either you control your compute or you don't.

Thats who linkedin draws. I used to exclude linkedin resumes when interviewing heavier linux engineering/ops candidates for this reason.
