@shcarl276 UBports doesn't have support, exactly because it's not a business; it does not deliver a service. What we have, as you noticed, is places where users try to help users. Places like this, and Telegram, and Matrix.
I have to disagree that
a functional system is characterized first of all by satisfying the needs of the overwhelming majority
I don't think that is true in general.
More specifically: Ubuntu Touch is not made for the overwhelming majority. It's made for the adventurous, the tinkerers, those who do not wish to join the mainstream, and those who wish to get away from Big Tech. We will in all likelyhood always be a minority. And that's fine.
