Is it legit?
Was this the same email address that was hacked a while ago?
If you think it was him/her/they, why didn't he PGP sign this message?
I don't think this is legit, and if he really wanted to give his opinion, don't you think he would anticipate people not believing into this message and because of this, he would have singed this message.
And spare me of that BS how Satoshi never signed his messages, this is way to important and I don't see anybody would expect that community acts on this unsigned message.
I don't think it is him because I don't think he would get himself involved in the blocksize debate.
Bitcoin is an experiment to him and he needs to see if it can work without centralized interference.
What is very interesting though is the email address, do we have any records of his vistomail being hacked or ever used before like this? It seems unlikely that a hacker gained access to his email to only post this and not try any other schemes with access to such an important email address.
Well seeing as his email address [email protected] was hacked, then we haveto assume that the vistomail one was too. Maybe the gmx.com email address was setup as a "recovery email address" for the vistomail account, so when the hacker compromised the gmx account he was also able to compromise the vistomail one via "forgot password".
If Satoshi were to ever return, he would provide significant proof that it is him with signed messages etc.
So the hacker just held onto the vistomail account for over a year and decided yesterday after Mike's article on medium.com was the perfect time to execute his attack of a post to the mailing list? Wouldn't the hacker rather try to profit by posting it for sale, or leaking old messages, etc.?
