Does it matter that it is still in beta? Gmail was in beta for a long time?

It's obviously not a "beta" version of the product in historical terms. It's a product that's being publicly used, with all of its imperfections on show, which is continuously being developed.

These are paying customers.

I would say that the actual software component of Minecraft isn't in beta so much as it's the "game mechanics" side of it. It's like having a board with pieces, but not all the rules are written yet.
