I think you are barking up the wrong tree, Zuckerburg isn't going to be interested in any partnership with Steemit, why you would think such is beyond me, the Winklevoss twins should be a fine example of how far Zuckerburg would view any partnership. I agree with most of what you are saying, Libra will dust Steemit in performance, that's because, as you stated above, that most people really don't concern themselves about current issues like the censorship debate on social media platforms as it doesn't effect them nor do they care about privacy when they view being on the internet in any fashionable form they feel tracked. Just about any site you go to you have to agree to let them drop cookies on you before you can participate on their sites, people have become immune to it. Now you offer up a cypto that people can use to buy product, like diapers and you have a winner, maybe even someday you will be able to even buy car insurance with it from a site on FB, who knows, but it will still be a totally different platform then Steemit, it will enhance the viability of crypto's to an audience of people who are just happy to post mom and pop pic's along with sharing meme's but it won't come close to offering the high quality blockchain ability of Steemit, there will always be a well educated public that will prefer that over posting random dumb stuff on FB.
