There is a difference between supporting Bitcoin and supporting the Blockchain. We saw R3 also supporting the Blockchain, and look what they are doing. They can just as easily,
chose to use any other Alt coin based on the Blockchain technology and then turn against Bitcoin, so I would not flip with happiness if I were you. The statement that Elon Musk made, does not neccesarilly mean that he supports Bitcoin, you have to remember that he had strong ties to PayPal. ^frown"
that is right and it is the first thing that came to my mind also. because history has shown that they are always talking about "blockchain" as a separate thing and never really support bitcoin.
but reading up on some of these news and what these people have said I can see they have also mentioned "bitcoin" and have been positive about it, not only talking about blockchain like the past and other people.
