Cloud Macros for Bitbucket and Confluence is the missing solution for users of both Bitbucket Cloud and Confluence Cloud.
Why not call it "Bitbucket Macros for Confluence Cloud"?
It's not that simple unfortunately. Atlassian have copyright over both product names. Starting the name of the integration/product with "Bitbucket" may infer that this integration is an official Atlassian product (which it is not), so another name is required. I believe that this name is good enough, at least for the time being.
