Facebook has a lot of years of mainstream adoption on Steem. That’s something we can learn from. But the problem with adoption on Steem is the level of apps do not quite live up to what FB, IG, and others can do. You’re talking mobile apps with video embedding and live-streaming from the app. You’re talking more than just photo filters, but 360 camera capability, and all the crazy video filters that IG and SnapChat offer in app. You’re talking private groups on FB. They just simply offer more and have a huge development lead that Steem needs to catch up ok. No Steem app offers these yet, and new features roll out quickly on mainstream social media.
The other part is the sign up process and in reality a lot of the content we see. And we won’t even talk about bid bots, and drama relating to disappearing acts we see with delegates Steem to projects that just vanish. All these things are red flags for new people in general, specially if they have a brand, following or reputation to uphold.
I'll agree with you in some aspect of your position, but truth be told, all those are possible from the billion dollar of gains they make from users. Libra is a "rob Peter and Pay Paul" scheme.
