I think it depends on how each org or company defines its team structure and the responsibilities of the different roles. We don't have a separate tech lead role in our team.

Even so, wouldn't a tech lead be focused only on technical aspects. Say if I want feedback on some customer interaction I had or maybe regarding a meeting I ran, it is not the role of the tech lead to do so I think.

Many companies want to save a buck and figure their best talent can become good-enough managers and still be that technical lead. It rarely works out.
