I have read those, and have built a few side-projects in Elm. There is a large difference between 'the community' as in the folks deciding of the future of the language, and 'the community' aka the huge majority of the users of the language. Elm has one of the most welcoming communities I've ever seen. They are ready to explain the same concepts again and again in their slack and many of them (quite a few being here in the comments actually) are not only helpful in Elm, but wholesome humans as well.

Elm is IMHO extremely friendly, especially to newcomers. The leadership style however is up for debate but that's another story.

I wouldn't bet my company on Elm personally, but I can't recommend it enough for side projects and folks interested in learning more FP or simply for fun.
