1) How often do you actually find yourself modifying the source for emacs? If you never do it, then it's not really important. And if you DO, then perhaps paid software, with a dedicated team of full time developers, provides a more stable experience out of the box that requires no editing. I have never felt the need to modify the source of an IntelliJ IDE, but much of it is open source anyway. And I can always write plug-ins.
2) IntelliJ has an IDE for everything. I use:
Pycharm for python
Webstorm for javascript
Datagrip for sql
Android Studio for Android
CLion for c++
And they all work the same. They have the same right click menus and keyboard shortcuts.
3) I started using IntelliJ products 5 years ago when Android forced the switch from Eclipse to Android Studio. I have NEVER, in 5 years, experienced what you mentioned. Not from the IDE. I HAVE, however, had third party libraries completely depricate their public API to replace it with something entirely different on numerous occasions (I'M LOOKING AT YOU FACEBOOK.) And in those instances, with an IDE, it was trivial to refactor my code to handle the underlying change. Even when the community switches gear entirely, IDEs help. When Android switched to Kotlin, Android studio added various options for converting your code from java, piece by piece. Sure the resulting code wasn't optimized, but it was good enough to work from. You're not going to get any of this from emacs.
I use vim daily to modify text files and remote source files, don't get me wrong. But an IDE of some sort would benefit most developers. From static code analysis that prevents runtime errors, to point and click breakpoints, to code coverage highlighting, to code macros, autocomplete, automatic PEP8 formatting, right click refactor, alt enter for auto import, spell check, etc. These are just everyday features that every developer could benefit from. Some of which can be made available in emacs or vim via plug-ins or using other tools, but it's far simpler to have everything in one place.
