That's the key problem here, people can't agree on what a blockchain is, and keep re-defining it to meet their implementation needs. If you think decentralization is fundamental you won't accept the enterprise blockchains into the definition, but the B2B companies aren't going to look at it that way.

This is what usually happens when marketing around a term gets too froth (see also, AI).

You're right and I don't want to get too far down the road of defending blockchain (as I seem to have unwittingly done). The marketing most certainly is over the top.
