I think a good compromise would be to enable users to download a Rise package of some description. 

I would see this package as something that could be stored offline, with the understanding that it is only editible online with an active subscription. I'm speculating completely here but where this might result in a drop off in people subscribing on an indefinite basis there's an argument that any lost revenue could be made up by those who are currently unable to subscribe due to the issue we're discussing being resolved.

I'm not sure whether this could work for anyone but maybe for developers who don't have a need to subscribe to 360 (perhaps they're working exclusively in another tool at a client's request or are a freelancer who's taken up a permanent role), Articulate could offer Storage 360. For a monthly/annual fee developers could extend the 6 month period that courses will exist on Articulate servers post-subscription expiry.
