I suspect the surprise is grounded in familiarity with the product and its content. You're an expert on sqreen. Potential customers are not.

A screenshot of a generic text editor juxtaposed against explanatory text probably should be considered burying the lead. The heading doesn't seem like a natural place to put technical requirements/limitations/implementation_details in the content hierarchy.

I'd add that the idea that the software is made by developers is something better shown implicitly than stated explicitly. It's mostly line noise to other developers looking at developer tools [I mean name a developer tool that wasn't made by developers].
