Do you have a license already?
I don't get people that have an Altium license and complain about subscription costs. Just get a perpetual license and don't pay subscription if its an issue.
We have a number of licenses. Our company is growing, and our usage has been increasing.
If you want or need any flexibility at all, you pay more. Want to move a license, you pay. Want to keep your versions sync'd, you upgrade. What's that, you didn't pay back maintenance? Oh, then you can pay all the annual back maintenance, then pay even more to upgrade. Want some flexibility, pay more for a floating license. What's that, you want to use your floating license at a remote site? That'll cost you more! Overseas, even more again!! Got a problem, found a bug? You're doing it wrong...
Maybe sticking to an old perpetual licensed version of Altium works in your situation, but it doesn't work for us.
