It is a point of the day and will last forever. I know you are not a first person who says about this but thank you for repeating it again.

Bitcoin is a decentralized project so on official website, wiki and so on. It matches with the original vision of Bitcoin creation and development. Just verify digital signature of Bitcoin Core as well as verify information from any site about it.

Honestly a few years ago, I thought Bitcoin.org is an official website of Bitcoin but I was wrong. If my memory is good, in the past, you attach a link to bitcoin.org for update of Bitcoin Core new version. After that, you switched to Bitcoincore.org and not too long after, I was enlightened by some veteran members here that there is no official website for Bitcoin.
