That’s exactly what I meant, they don’t need Threads, it’s all public (except possibly email addresses?) , but @bighi commented to me and said it doesn’t work that way, so now I’m secend guessing myself.
Either way, they can scoop all that post data up anyway, to me the data is almost becoming a red herring. IMHO, Facebook’s history of being a platform of hate-fueled content, violence, trolling, social manipulation, etc. is of greater concern.
I’m also wary of the day that Facebook is the driving force of the Fediverse due to it’s sheer size. All those users come along with a great deal of inertia, and Facebook could end up being the mega-Corp who decides all the protocol standards forcing others to keep up with their “contributions” or get left behind.
