The title is needlessly inflammatory (hope that's the right word). It's the original one, but the article states clearly that it is an advice for libraries that are intended to be used by thousands of developers. Maybe the title could be changed to "All big JavaScript libraries…"?

What's a "big" JavaScript library? How do you know how widely adopted your JavaScript library will be?

Regardless, it's difficult to think of any situation where a All _______ should use _______ is really justified.

It works for "people" and "common sense".

Depends on what you define common sense as and the context you are using it in.

All APIs need good documentation to be good APIs. If you're not providing good documentation with your API you're doing your users/consumers a disservice. Using a tool (TypeScript/Flow/whatever) to ease the pain of providing that documentation is in the best interests of an API developer since it reduces the friction of having to write the documentation by hand. Also, in this case, good documentation is not just documentation for the programmer that is consuming the API, but also the IDE within which the API is being consumed.

I'd say in this situation the title is justified.

All libraries should use input validation to avoid RCE and other attacks

All software that handles sensitive data should use transport encryption & encryption at rest

All software that uses encryption should use thoroughly vetted professional crypto

All computer users should use backup software

It's another click baity title like "Why we stopped using [popular X] for [less popular Y]", "[Popular X] considered harmful", "Why you shouldn't use [industry standard X]" etc.
