For example, many developers despise React.js; I once interviewed for a dev role for Facebook years ago and they asked me if "I had any qualms about using React" (paraphrasing) and the interviewer acknowledged that many candidates did not like using React... Yet React has a near-monopoly on frontend frameworks.
The whole media landscape around open source dev tools has been a nightmare. We're being pushed in specific directions, towards a small number of silver bullet solutions which do not suit most use cases.
It feels like all the authors of popular tools form a corporate insider clique and no tools outside of that social network is allowed to get any traction at all.
