It is similar because of how it happened. There are lots of people using the code for various reasons and many of them participate in the community or contribute patches. No one else that I know of has engaged in a conversation and then refused to reply to any further correspondence while at the same time asking questions to the community under pseudonyms. Like the OP what the other company did was probably legal. That doesn't make something okay or right. Likewise (as I admitted) this other company didn't break any laws. But that wasn't the point. You know what would have been okay? If they said, "look, we have some engineers that are going to have a go with the code - let's keep in touch" or "we are going to fork the code but will submit patches back". That is the spirit of the MIT license. Be civil. Hope that doesn't come off as negative either :).
