They are not copying satoshi. What they do is trying to avoid future implications if they have bad thoughts and results about their project.
No one will be followed, no one will get sued if the team is anonymous. This is why it's good to follow those projects that has a known team and is composed of people that has experience in cryptocurrencies, not just the typical expert that the media says.
I agree, thats the reason why they chose to be anonymous.
But we know its important for the team to become transparent.
So we can check their background and projects hold.
Anonymous team of the project is likely a scam so stay away.
