My favorite is the hobbyist youtube videos sponsored by Altium. Just pay 10k plus 2/3k per year afterwards and you too can design boards like I can! (/s)

But the reality is I unsubscribed from those creators, because I never want to see someone design a board in Altium, I want to see how they build a board using kicad.

From the software side, I really like the license model of the all products pack from JetBrains. And it goes with me wherever I go.
