Open-source your product, let me use a custom domain (so that I can still keep my URLs alive after you belly up), and then I can reconsider, but, for now, Ello is not much different than the rest. Hates and likes change, plus, VCs can twist arms (or show you the door) - let's cut the BS! The premises I listed are still not enough though as it won't keep my interactions with people who are either unwilling to self-host later or who picked the default domain. Maybe transfer the ownership of the main domain to an independent nonprofit entity to ensure life-after-death?
