Liability shifted onto the user
You are agreeing to limit the company’s liability and, in some cases, to indemnify it.
“SLACK MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY KIND, WHETHER EXPRESS OR IMPLIED, TO YOU RELATING TO THE SERVICES, WHICH ARE PROVIDED TO YOU ON AN “AS IS” AND “ AS AVAILABLE” BASIS.”
What that means: If the service harms you, the contract tries to leave you with little recourse.
Liability is shifted toward the user through waivers or indemnity.
