They're not really exclusive ideas. The Constructor Injection section in Fowler's article is exactly the same as the Strategy pattern. But no one talks about the Strategy pattern anymore, it's all wrapped into the idea of DI and that's what caught on.

I'm curious, which language/dev communities did you pick this up from? Because I don't think it's universal, certainly not in the Java world.

DI in Java is almost completely disconnected from what the Strategy pattern is, so it doesn't make sense to use one to refer to the other there.

It was interesting reading this exchange. I have a similar understanding of DI to you. I have never even heard of a DI framework and I have trouble picturing what it would look like. It was interesting to watch you two converge on where the disconnect was.

Usually when people refer to "DI Frameworks" they're referring to Inversion of Control (IoC) containers.
