Correct. I don't think the CEO of Y can ever say "I'm the CEO of Y and here's a link to a blog on Y company website about something related to Y company that I think is worth sharing here" and have it be astro-turfing for Y. It might be advertising or even spamming. It might become too frequent or annoying or otherwise negative.

I follow TTN (and Helium), have a TTN gateway plugged in, and a dozen or so LoRa dev boards sitting around (two are within reach, albeit buried under some dust of recent disuse).

I find the LoRa tech interesting in general and a new RF distance record specifically interesting, whether it's on the TTN blog, the Helium site, on an Andreas Spiess video, or elsewhere. It sounds like you have some relevant history with the company's behavior that is shaping your opinion of their action here. We perceive their action here differently as a result.
