Obviously no what I mean that is ok if your superior and his boss are invited in your team's slack channel even if they only lurks, and you don't create a "shadow channel" with your teammates to talk on the project without being read by your hierarchy.

Same thing with corporate internet, you accept to use the corp proxy DNS and firewall (which all logs infos) to browse the internet instead of using a separate GSM endpoint to circumvent the company's surveillance.
