All my "meh" comments gave me a 💡: What if the blockchain itself is used for *versioning.* In a social network like Memo you could curate to edit what is displayed on your post.
I mean, create a new post as a new TX's data, but then have the option on the front end to curate... maybe even micro-TX's for being able to "undo"? "Deleting" would be for display.
I really don't think it matters as to which one is called the real Bitcoin. The only thing that matters is which one has cheaper payments, faster, and can benefit the globe.
