I don't want to sound like a cold-hearted jerk, or just a blind fan boy who thinks Tim can do no wrong, but his words weren't personal (not even the "jerk" one -- although I can appreciate that must have stung for you) because simply: He doesn't know you. He was just upset by something that was triggering for him.
It seems he felt like you were saying he didn't deserve to have his name with the title... Which undoubtedly reminded him of the executives he fought back in the day -- ones who probably literally told him he didn't deserve it. And being able to take creative ownership of his work obviously means a huge deal to him as he risked everything he had to set up his own company to do just that.
Plus it's easy to think of people like Tim having thicker skin than the rest of us. He's got all the power, right? Hundreds of thousands of fans, etc. Famous. Successful. Celebrity friends. Interviewed all the time. But you tend to find that these people are just as insecure and touchy as the rest of us -- if not more so.
For example, you often hear comedians, even from the hugely successful ones, talk about how one audience member can upset them. They'll have thousands of people laughing... and they will laser in on the one person who isn't. In their heads they'll be wondering, "What's wrong with that guy??" It seems it's human nature to let that one voice upset us, even when everyone else is saying we're great.
So yes, technically, he called you a jerk. However: 1. You're not a jerk. And 2. Tim was just being insecure and touchy... like all humans can be. I'd try not to take his reaction personally and try to cut him a little slack: From his point of view, you were a person trying to take his achievements away from him.
