Ehm sorry but no. CRM stands for Customer Relationship Management so … a support ticket is, by definition, a customer relationship event.
Salesforce spending millions to conflate “CRM” with “sales pipeline” was just marketing.
Also, Zendesk calls itself a CRM. Freshdesk’s parent is literally named Freshworks CRM. Gartner and Forrester have always put support under the CRM umbrella.
