Good question, I just had a look at Garmin's API brand guidelines, and it sounds like all API consumers will be affected, as it states the following:

All uses of Garmin device-sourced data within dashboards, activity feeds, overview cards or summary views must include a “Garmin [device model]” attribution. This attribution ensures brand clarity and traceability. Access the device model information as instructed in the applicable API documentation. If the device model is not provided or unknown via the API, list Garmin as the data source.
