CGL has used KS in the past:
The DukeI don't believe the issue is in needing funds to support development/production of new SR material (though I've argued that Sprawl Gangers would be a very interesting candidate for KS). CGL is a small company that makes extensive use in freelancers already...the challenge ( MY opinion) is that all that material ultimately has to funnel back through a finite group of people (some of whom also support BT, Valiant, board games, etc). I'm not sure crowdfunding would ever really change this...again, my opinion.
With regards to Patreon, I'm not a huge fan, but I do think that some have made excellent use of the platform to deliver great material. Now, if someone were to take on a "fanzine" project and use Patreon to source funding to pay for content, artwork, editing, etc...that would definitely pique my interest. Of course, not sure how the licensing would need to work (or if it would be needed), as that would need to b discussed by/with CGL.
