The only official site is created by the main developer or satoshi nakamoto

But, some people don't care about official bitcoin site
But i think people need good webiste about bitcoin (bitcoin.org / bitcoin.com / bitcointalk.org) where there are lot people together

They probably have good intentions. If they wanted to make a quick buck they would just sell the domain
So, they claimed to be official site & sell the domain for some fiat
What happens when the owners die and their heirs get control?
In any case the issue is resolved and the new description is on Google:
"Bitcoin is an innovative payment network and a new kind of money. Find all you need to know and get started with Bitcoin on bitcoin.org."
