Ask HN: Why is Sublime Text so expensive and who pays for licenses?

Sublime Text is great, so I suspect many users would happily pay (or donate, if given the choice) $5-20 for the privilege of such a tool. Sublime's asking price is $80, however, and as a result no one seems to pay (even large corporates).

I'm curious 1) why Sublime doesn't allow smaller payments from devs who want to support the project and 2) what entities are actually paying for licenses (government, companies with strict procurement rules, &c.)
