This is so atrociously written that it can only be done by an altium employee.

Several initiatives such as EAGLE have attempted to fill this void, releasing restricted versions of semi-professional EDA tools. The rise of KiCad further fragmented the market. This pressure eventually provided the incentive for Altium to release a simplified and more user friendly version of their professional EDA software package and flagship product, Altium Designer, targeted at less complex circuit board projects.

I'm a happy KiCad user myself for some 7 years and counting, and I value my freedom (for as far as that's possible in this constrained world), and that alone is enough reason for me to not use that mist based software that keeps your designs as a hostage on someone else's server. Who knows when they'll pull the plug out of that server, and poof, all your effort has evaporated.
I've been thinking about deleting this post as I don't want to make a KiCad vs. circuitmaker rant but the "incentive for Altium" to "fragment the hobby & small company PCB design market even further", and present themselves as the savior of open source project is too mind mindbogglingly misleading to let it slip. There is no altruism in altium.
Have you read this thread (Spoiler, there are not many happy people there):
https://www.eevblog.com/forum/circuit-studio/circuit-studio-dead-(again!)/I am curious though why you're interested in circuitmaker, (Or more interested in circuitmaker then in KiCad).
