There are many crypto projects that are building a community around their product.

But can you name the products that were born out of communities? 

When the original idea was really to create a community of like-minded people, not to create a community for further sales.

Exactly! I mean when the original purpose of the community was to collaborate and bring like-minded people together. Not marketing around a certain product.

But then the community reached the point where it decided to release a product that solves the community's problem and meets its ideology

Negative. Community building and product building are very different skills.
