- I most likely would have not started using Altium if would have not been exposed to a pirated copy two years earlier by another engineer. Would have used more expensive alternatives instead (Cadence/Mentor Graphics/Zuken).
- At <10k and <2k subscription this tool is very well priced. (Compared to salaries and prototyping costs). I have also used more (10x) expensive tools and can say in many aspects those are not better. On the contrary in most cases.
- The hobby needs are quite filled with GPL3 licensed KiCad it was not always so. I would still not use KiCad in a professional setting as a main tool, but that may change as KiCad has made huge progress ever since CERN started using it. However, CERN electronics development guidelines still have Altium as preferred option. Altium is just much better tool for complex electronics.
- Altium has cheaper CircuitStudio now as an option, that was a very reasonable compromise last time I looked. Also they have free CircuitMaker for tinkering and hobby use, which I have not used so can not comment on.
As an aside, I've always found software at this price level to be a bit of a paradox when it comes to piracy -- Altium, Autodesk Maya ($1620/year, currently), and similarly priced vertical market solutions are big fish in tiny ponds. If you're in a business that needs Altium or Maya, you're almost certainly going to pay for it, and conversely, folks who pirate software like that almost certainly don't need it. If I ran such a software company I don't think I'd bother with DRM; your true copy protection dongle is (or at least better be!) the level of support you're giving licensed customers.
So what? Does this mean I shouldn't be able to play with the big boys' toys? I certainly am not skilled enough to get to the break-even point where I earn back enough money to cover the cost of the program.
For me personally, if I was actually going to be using niche software like that to make things I was going to sell, I would not be comfortable doing it with pirated commercial software for both ethical and legal reasons, and I would look for adequate cheaper alternatives, only moving up to Altium when and if my sales justified it. This is why I don't actually own or use any Adobe software anymore -- it's less niche, to be sure, but I wouldn't use Photoshop and InDesign nearly enough to justify the price of Adobe Creative Suite. And, again, personally, I don't feel like "but I'd use them occasionally and I wanna use the big boys' toys" justifies me pirating Adobe's software rather than finding much cheaper alternatives that I still like.
