KICAD is free for everyone? Even including corporations?

No company owns KiCad so there is no one to be paid, but as said, its license must be respected.
Regarding other companies using KiCad, you can follow this thread:

Is KiCAD used in the Industry?

I work at a small company and we create/edit about 2 PCB boards per year. We currently use Orcad 16.0 but need to upgrade and we are looking for cheaper options. I am wondering if any other companies are using KiCAD to create PCB board designs and if it is stable enough to rely on? Note: It has to be worth it and reliable, once we switch it will take us a lot of time to transfer over the designs from Orcad to KiCAD. We also don’t want to be switching from it in the future.
