I've only read the first few paragraphs but I've noticed a narrative issue. I might be the only person to have this peeve, but when introducing a story to non technical and even technical readers, it's always clearer to introduce which website is not theirs and which website is theirs. It's written in a 3rd person perspective that doesn't take ownership of the websites.

"Only Melbourne and Adelaide radiosondes (the transmitter on weather balloons) were being tracked on a website called Habhub - high altitude ballooning hub."

Ok, I can infer that habhub probably isn't the speaker's website.

"A query parameter could be added to the URL to remove the filter and on 12th of May 2018 sondehub.org registered with a single purpose - a URL redirect to Habhub with a radiosonde specific filter."

Ok, I can infer sondehub was set up by a jokey duo or group of weather balloon hobbyists.

But it's really annoying reading and doubting this because I'm not 100% sure that the speaker is actually the domain creator of sondehub.

You can say "we registered sondehub" or "I registered sondehub.org." Poor journalists use this passive voice sometimes. "Something happened. A source said..." Unless you're protecting a source, you can say who said what, and what caused something to happen.

So I stopped reading, and wrote this comment.
