I agree with you community is everything
because in my opinion bitcoin can become what it is today it cannot be separated from the role of the community because with a community a coin will be recognized by many people more quickly and in my opinion the community is the best promotion place.
All these companies clearly need a community because having a large community will definitely make marketing easier and wider because it can also really help companies in introducing their products to the general public, as in the example you said, so that until now Bitcoin is still becoming famous.
