that number 1 problem isn't a problem at all. the work is there, it may be continued by anyone else, and if people find value or interest in it odds are it will be. that is what open source is all about, power to the people.
what's wrong here are your expectations, and also your logic: you are asking from open source projects much stronger guarantees than closed source enterprises ever provided. we regularly get news here about startups closing or products getting discontinued and any users or customers being left in the cold.
to illustrate, i own a hp reverb g2 vr headset. it builds on windows' "mixed reality" runtime. microsoft is just about to discontinue that component and hewlett-packard already stated that they "can't" and won't have a substitute for it. those are all paid products, but that excellent and perfectly working piece of hardware is about to become a brick coming next windows update
open source is okay, it's likely the best thing that has happened to software (and hardware) ever, has had a huge impact in general and doesn't need your endorsement or approval. just stay away from it if it's not to your liking for some reason. good luck with your dependable providers.
