So I'll counter an anecdote with an anecdote, my dad is a draftsman by trade and was an engineering technologist for decades, he's looked at Freecad back and forth and is now seriously looking at it over solidworks for his personal projects now that he's retired, I also flipped from solidworks which I used professionally for about 5 years before changing roles. Does it have quirks, yeah it does, but so do other cad packages, and lets not pretend that solidworks is a beacon of stability, there's a reason it was drilled into us in uni to save frequently and why it has autosaving. The UI is relatively simple, there's plugins to customise it and it has substantially improved over the last decade when I first gave it a try, way better than my memories of using solid edge (and I personally disliked fusion, just didn't click with me, at least freecad has a near identical workflow to SW). Am I more accepting of jankiness with Foss solutions, straightup yes, it's provided for free without restrictions on its usage vs solidworks where if you have a maker license for example, only other maker licenses can open the sldprt file.

Another example, I'd wager it's why you see a lot more r and python usage in statistical spaces where SPSS and SAS were used because those tools are extremely expensive for licenses (I recall a colleague talking about it costing 10s of thousanda at leaat, maybe more, company was always looking into ways they can get off of it) cost alone makes the Foss solutions more accessible.

I'll be also fair that both of my anecdotal examples we're using for personal projects but the point is that professional users aren't a monolith.
