Also the definition of technology is not "does something with or on computers", it's "the application of scientific knowledge for practical purposes, especially in industry".

A car is a piece of technology. An engine is a piece of technology. A computer is a piece of technology. A technology company is a company that produces products that are the application of scientific knowledge for practical purposes.

What we're really talking about is information technology, which is the study or use of systems (especially computers and telecommunications) for storing, retrieving, and sending information.

It seems to me that excludes all software from "tech". The computers are tech, but how they are configured isn't "making" anything.

It doesn't seem that way to me at all. You can create software that does things that were previously not possible or not practical. That is the creation of technology. Software and information are products just as valid as cars and robots.
