Being popular isn't a synonym for quality.

It proves that there was a need not met by other options. Do you resent Atom developers for giving away free tool that you consider subpar? Or are you angry at its userbase for choosing Atom over your preferred option?

I don't use Atom but I'm glad it exists. It improves on state-of-art in some areas and that benefits everyone.

Yes, because of Atom many developers probably won't be giving money to e.g. Sublime Text or any other commercial alternative.

This is why good tools are only available to enterprise customers, the only ones willing to pay for their tools, just like in other professions.

There is nothing in Atom that I can consider state of the art.
