I have been coding for 30 years now and I have never encountered a technical decision like choosing technology (e.g. Electron) for anything important to the company being made with "oh, we must use X because so and so knows X"

Maybe if there was a toss-up between X and Y or something like that but to flat-out pick Electron because you have people that knows JS is madness

I'm thirty+ years in too, and it happens all the time - particularly in smaller operations. Resourcing constraints, disinclination to provide training, tight deadlines, etc.
