Bitcoin (BTC) is Bitcoin. Saying it's "altered" is like saying that Hacker News is "altered" because its code has evolved over the years. Saying BSV is the "restored" Bitcoin protocol is like saying retrohackernews.com is the "restored" Hacker News because it runs on an old fork of Hacker News. That doesn't make it Hacker News.
I'm not saying that Bitcoin has become good or bad; I'm saying it's Bitcoin. BSV folks spend a lot of time and bytes trying to convince others that they're the real deal, and that Craig Wright is Satoshi Nakamoto. It doesn't matter. If BSV is superior to Bitcoin, it should prevail through its own merit, not through language gymnastics in online forums.
