I would not use the term scraping. Oaknotes directly reads the XML data that Mission+ uses. One could argue that the XML data is the true source document and Mission+ and Oaknotes both display this XML source data. The Oak Notes code was visible and available for inspection. Having seen some of the Mission+ errors in SkyHub, I would have more faith in Oaknotes. While not a safety item, Mission+ cannot even calculate the correct times for Enroute Information -> Key Info/Activities during flight.

The accusation was made that Oaknotes hides data. The specific complaint was that Oaknotes was graying out notams were it interpreted the NOTAM to be irrelevant due to the date/time. However, Oaknotes still showed the NOTAM in gray font should the interpretation be incorrect. There is a discussion on SkyHub. Speaking of hiding information, one of my pet peeves is how Mission+ behaves if you have two alternates, the second alternate does not show up in the FDRA, Flight Information or fuel planning. You can only find the second alternate in In Flight -> Final Alternates or clicking on All Alternates in the dashboard to get to Final Alternates.

Oak Notes is good. However, the big picture is that Oak Notes was popular because Mission+ is such poor quality.
