You could also introduce some that could be stuck on corpies as a way to allow those corpies to get nailed for committing crimes without necessarily having to lose their jobs. Part of the difficulty in playing a corporate character is that you spend a lot of time building long term RP in a specific direction that goes out the window if you get fired. This would add an option for WJF or execs to 'salvage' an employee while making it clear to the public that Justice has been done.
These wouldn't be coded beyond the implant itself as a piece of cyberware, but it'd absolutely be expected that players who didn't play along would get in trouble.
Off the top of my head I can think of implants to prevent people from telling lies (though they could choose to remain silent or weasel their way out of questions that were not carefully asked) and implants to enforce absolute loyalty to whatever Corporation sponsored the subject's citizenship. Bonus points if these implants are visible at a glance, like a little metal doodad stuck to someone's temple.
While players could just BS their way out of these restrictions, I assume that staff is pretty careful about who they do certain things to. Anyway I think it would be funny.
