What is the organization subscription notification within ticket events?

Question

What is the organization subscription notification within the ticket events? How can I disable the notifications?

Answer

When viewing the events of a ticket, there is an Organization subscription notification:

These are ticket notifications end users receive when they are members of a shared organization and follow an organization under My activities within the help center Customer Portal.

To prevent these notifications on tickets, update the organization to no longer be shared. To unshare an organization

Edit the organization's settings by following the steps in the article Editing an organization

On the organization's detailed view, select Can view own tickets only in the Users field

Even if the organization doesn't allow it, the user will receive notifications according to their personal settings.

The user-specific setting that lets someone see all tickets from their organization, overrides the setting of the organization. That means that even if the organization is set to not allow it, the user will still get those notifications if their personal setting is configured to enable this.
