Maybe, stop and think before you ask this. Someone offers up an example of their hard work and you instantly accuse them of being a malware author that steals your data. Nice.
I would rather call it the new-found paranoia most legal departments now have, when IT dept. mentions rolling out new, unknown, non-auditable software in the company from a new vendor that wasn't grand-fathered in (= the legacy windows/cisco deployments). I'm happy about it. I'm just waiting for them to forbid closed-source firmwares/hardware.
You could block it at the firewall - same as you would for any application.
