Exactly. The issue of "Bitcoin not being the original Bitcoin" is just propaganda from competing chains than anything else. We all know both BCH and BSV want to take advantage of the situation by taking Bitcoin's place in the market. With these claims, both BCH and BSV will be able to fool most newcomers into crypto making them think that they're the real Bitcoin. Code changes do not reflect a deviation in the vision proposed by Satoshi himself. After all, it's necessary to make improvements in the code to maintain the software up-to-date and resistant against the latest threats in cyberspace.

Bitcoin may not be the same code-wise, but it's still the same Bitcoin protocol Satoshi created a long time ago. The unaltered history of transactions since 2009, speaks for itself. The ones that are NOT the original Bitcoin are BCH and BSV because they've forked from the main Bitcoin blockchain. A fork is just a copy of the original software's codebase. And both BCH and BSV are simply altcoins with a different transaction history than the main BTC blockchain. Considering that they're both extremely centralized, they go against the Blockchain's value proposition of decentralization/censorship-resistance.

Nonetheless, this issue is more of "crypto politics" than anything else. Just as it is in real life, political parties have different visions and proposals in a specific country. The same thing happens with Bitcoin where a group of people believe in scalability, while others believe in decentralization/censorship-resistance above anything else. The fight between Bitcoin and its forks might never end as the crypto space has become politicized by its own leaders (Roger Ver, Craig Wright, etc.). Just my opinion
