While some people might be reacting based on simple entitlement, I suspect that for the majority this triggers a strong reaction because it is a warning sign. If Docker were a big company, it'd just be part of the normal drift toward customer abuse. Because Docker is still a relatively small company, it looks like a desperate attempt to stay afloat through increased monetization. The unintended side effect is that it makes me less inclined to purchase anything because I don't want to bet on a sinking ship.
