Example to explain above question:
If my company sells a product to a client that includes a font found and used through fonts.adobe.com and the creative cloud subscription,
would they still be usable, if used on a website, after cancelling the creative cloud at some point?
Would it still be legal to use them? (no redesign, just our customer keeping to use the product we provided him back when our company had the creative cloud subscription)
use.typekit.com
style sheet), then no – that style sheet will lead to a 404 once the subscription expires, and the fonts will not load. Even if you downloaded and copied the fonts, that in itself would be against the EULA. ‘Legal’ is a fuzzy term; your EULA is what matters here.
