By that are they only restricting adding the font as a selectable font for writing (i.e. WYSIWYG editors) or can you not use the font in your own software in any case?
In short, the license covers your use in the software, websites, mobile apps, etc you create. The limitation is to prevent distribution to your software's users. For example, if your product was a CMS, you could embed SS in your app's UI, but you couldn't give it to your users to embed in their own websites without an extended license.
Isn't that an inherent requirement of using the font in software/websites/etc? If I have, say, an open source CMS, I'd have to ship the font somewhere with the code to be able to use it in the UI, no?
They are licensed to you for use in your own apps, to display them, but you don't have the right to pass that on to others - pretty straightforward. Bad legalese, that's all.
It LOOKS like they're trying to prevent WYSIWYG editors from using this font, but it also looks like they'd prevent me from adding it to an app I was shipping, by virtue of only allowing it to be embedded in a DOCUMENT.
Even most free font licenses get this wrong; they seem to WANT me to use it and redistribute it, but the way it's worded I can't. Sigh.
At least most new free fonts are using OFL now [1].
