One codebase catchall. Most apps need some sort of web version and desktop version. So doing it all in web tech makes sense. Then as you get familiar with web tech doing it in native toolkits requires you to learn new paradigms and quirks which is a barrier to creating new apps so people revert to what they know (web tech). It's just that web is so popular so people stick to what they know. Same reason people would use say python with c extensions over golang. Even though go is faster out of the box, if they're used to the python ecosystem it makes sense for them to prototype in python and then optimize with c extensions, they can get something that works with less cognitive friction.
