Well, this is something one can be worried about in case of pretty much any software project. I'm not personally worried about Star Citizen funding neither on other crowdfunded project I have supported. I'm glad Ubisoft has been supporting BG&E2 this long time and CDPR doesn't hurry too much with Cyberpunk 2077 either. It is great there are still developers who are able/and willing to give their project development time.
Techincal issues are much more interesting in my opinion; server side OCS, persistence, server meshing, etc.
