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.
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.
