I agree. My point wasn't necessarily that they should charge for storage but more so allow the community to support them financially as they're working on their product(s). The post saying, "we're not collecting money, we're not trying to make money right now" just seems kind of strange. Keep the free model. Let people play around, but I still don't see harm in allowing someone from the community to pay keybase for working hard on a hard problem. I'd be more than happy to pay them right now just because I love the work they do and want them to succeed.
