You are supporting my point here. You aren’t selling actual tech, you are selling your website, that goes on to describe tech. No one puts out ads for things like c, bash, python, R, whatever. There aren’t billboards for these languages on the highway. This tech stands on its own, and people are guided to one language or another based on either its own technical merits or their own comfort with the language. You could argue things like white papers describing a technology in a relevant publication might be an ad, but I disagree. Those are more or less factual reports where the authors might even test their technologies shortcomings and limitations compared to existing offerings. Hyperbole is rejected by peer review, yet its the default language of advertising.

Ads on the other hand often lie by omission when it comes to the limits of a technology being advertised. They exist to get you on their product simply because the business is leveraged in it, not because its a good product, much less to share findings with potential colleagues about what you’ve discovered that might even tarnish said products initial expectations.
