I've just acquired the Hypothetical Cafe (come and visit, we serve great hypothetical food and drinks), and some fancy posh glasses*. They're so posh that an international designer did a special design for them. However, because he hasn't been to Open Source Stack Exchange, he doesn't know the wonders of open source, and kept his design to himself.
However, I've now exhausted my hypothetical budget buying them, so I'm going to have to serve open cola instead of Coca-Cola.
When I put my open cola into these fancy glasses, I am essentially producing a consumable product with mixed licenses. I am then charging H$0.98 for the production and cleaning of this product.
Technically, is this legal? I'm charging for the use of the glasses, which seems a bit legally iffy - or am I covered because people only consume the open part not the proprietary glasses?
* Disclaimer: glasses are actually from Ikea.
