login based license possible?

Hello all. I'm a big fan of Painter and so far have used essential versions of it. What prevents me from buying a copy of full Painter software are 3 activations. If a want to use Painter at home, on the laptop, at work, and change operating system sometimes due to computer upgrades, I will quickly use all activation attempts. Other software that I also use such as: the Foundry Modo, Zbrush, Marvelous Designer, Substance Painter and Designer  all have login based licenses which do not require activations. Affinity Photo and Designer have activations but they are unlimited.

I'm wondering why Corel Painter still only has 3 activations limit and why activations in the first place?

Thank you
