In the case of WidgetSmith and probably also Copilot, the subscription in large part pays for API access. For instance, WidgetSmith and WatchSmith (by the same company) lets you use features that don’t require external APIs for free. But stuff like weather generally costs money. In the case of Copilot, the investment tracking features almost certainly require access to a third party API.“Premium Subscription” is 4 out of 5 listed.
Detest subscriptions.
