You cannot expect, only hope. Remember, the @Bitcoin Twitter account was anti-Bitcoin, pro-Bitcoin Cash before, spreading propaganda "for Bitcoin", but not actually for Bitcoin.
Why? You want people instead to go to,
https://www.bitcoin.com, and buy the "other version of Bitcoin", expecting to buy Bitcoin?
Hypothetically speaking, if we want to promote the idea of Bitcoin and internet freedom, in case of a domain owner willing to turn a Bitcoin-related one into an anti-BTC campaign should be free to do so without being censored. Guess it's also why a lot of BSV shills are still on here promoting it.
How does it really help if theymos copies bitcoin.org to bitcointalk.org? In case bitcoin.org turns into a crappy anti-BTC propaganda, that'll open up a big door for whoever wants to start another website and promote the real coin and the legit information; the new website with legit info will also be added to whatever big website is currently promoting the "bitcoin.org" links.
Even if bitcoin.org changes and theymos copies the current website, absolute newcomers will still initially believe the "bitcoin.org" domain is the legit one. So the only thing really changing is that you now have 2 different domains, that's it. Newcomers will not know which is the legit one anyway - the only ones knowing about this change would be
us.
