This is a big issue for a client of mine, please fix this fast.

This affects Server as well.

Can this request be more broadly defined? Atlassian usually goes to the exact request and then there are impacts elsewhere in funtionality and additional requests needed.

In our case we want only the admin and/or the agents to be able to do this; however I think building this feature for flexibility would have configuration options for:

Removal by one or all of the following:

• Anyone
• Requestor
• Participant
• Agent
• Admins

Are all valid use cases.

We manage Jira and SD instances of an IT company who serves many banks and they heavily depend on Service Desk and use organization as a main part of their SD operation however when a user removes the organization from a ticket this interrupt their support operations easily. Please consider a solution for this request.

This is really a big issue for us , and requires fast action and solution 

I completely agree, even the ability to view other customers sharing the same issue might be a security/privacy problem

Yes, definitely. We want to create Problem tickets that are shared among customers, but want to remove the access of one customer deleting another customer from the request, and ideally, even viewing what other customers share that Problem ticket.

Adding the Ability to remove the "Shared with" section from view entirely would be another really helpful feature.

This doesn't make any sense, why would you want to do that?

This is a massive issue for us, def needs to be fixed ASAP
