Idk, I had a free open source command line project that scraped flight data and that got shut down. It might have been the particular airline, though, because they specifically disallow scraping from all third-parties including eg Google Flights, SkyScanner, etc.
Interesting. As a consumer, I'd love to see something in that space. I hate paying for most things, but a desktop app that allows me to search for rewards miles would be something I would pay a yearly fee for.
