While I completely agree with 90% of your comment, that first sentence is gross hyperbole. I have used a number of pieces of open source options that are are clearly better. 7zip is a perfect example. For over a decade it was vastly superior to anything else, open or closed. Even now it may be showing its age a bit, but it is still one of the best options.
But for the rest of your statement, I completely agree. And yes, CAD is a perfect example of the problems faced by open source. I made the mistake of thinking that I should start learning CAD with open source and then I wouldn’t have to worry about getting locked into any of the closed source solutions. But Freecad is such a mess. I admit it has gotten drastically better over the last few years, but it still has serious issues. Don’t get me wrong, I still 100% recommend that people learn it, but I push them towards a number of closed source options to start with. Freecad is for advanced users only.
