This. I've used a couple of packages and AD is at the top of the line. Design is a pretty difficult problem to solve which is one of the reasons FOSS, which is usually created by a limited amount volunteers in their free time especially for niche branches (i.e. not like a kernel for instance), has trouble catching up with the work of larger amounts of full-time paid jobs which are focused on just one thing.
Altium announced the intention to launch a lower-end tool (along with a new pricing model) a while back [1].
Presumably it's an entry-level product following a pricing model like EAGLE; limits to commercial use/board size/number of components/ layers/connections /schematic sheets.
There is no such thing as free. There has to be a catch. They are expert milkers.
