If they have a valid point, then one wonders why they wouldn't contribute "good new features" that offer a "fun experience" to the existing Facebook alternatives, rather than creating YAN (yet-another-network).
@indi In other places they have made good points about how complicated decentralized SN are for regular folk to setup or find interesting content on. I agree with them. I will never get my friends and family to actually use it.
While the underlying tech would allow for features to be built on top, it's limited if other people cannot interact with it. I think MeWe and OpenBook might be in the right track to delay decentralization. Wire too. Though OB is OSS and GDPR export ready and EU based.
