In order to get anywhere *near* hiring managers, you HAVE to say something about your expertise with the tool chain that they want to use.
It's QUITE rare that not even a casual commitment has been made to certain technology.
And you cement your reputation with a new prospect by appearing to understand the ins and outs of that technology.
The hiring party is already "general". They NEED and WANT "specific". It's reassurance that the person can deliver.
However, the gist of what you are saying is correct. A garden variety techie is obvious about wanting the chance to flex his technical muscle. The higher paid senior type will talk "whys", planning, strategy, how much money they have to spend, market windows, etc.
What you say is also correct,
IF you are talking to certain levels of management.
The higher the level, the more business-y presentation is needed. And vice versa, as long as you keep yourself above the level of the really nerdy types, whose pay grade you don't want anyway.
Better to be a "tyre bowler".
