Yes, the SFC doesn't allow the usage of the term "git" for third-party products unless they have their permisison.
From the Git Trademark Policy, 2.3 Prohibited usages of the Marks:
In addition, you may not use any of the Marks as a syllable in a new word or as part of a portmanteau (e.g., "Gitalicious", "Gitpedia") used as a mark for a third-party product or service without Conservancy's written permission. For the avoidance of doubt, this provision applies even to third-party marks that use the Marks as a syllable or as part of a portmanteau to refer to a product or service's use of Git code.
