It is not a fork aiming to replace it. It is rather a spin with saner defaults to cater to companies as customers. The product which shall carry ondsel financially is their freecad compatible cloud offering, and the hope is to use that for elevating freecad itself too. They need their spin to be able to ship an ootb experience fitting their motive and brand. So if you would like a less confusing experience it might be something for you. Currently there’s a lot of borderline deprecated and also redundant functionality in freecad, so I hope that ondsel’s cleanup mantra will make it to the ootp upstream experience as well.
