It's hard to stay in business selling something for $0. Meanwhile, there are companies with more money than $Deity that look at $10K as a rounding error compared to their high-end engineer's salary. So Altium follows the money. As a huge open-source nerd, I used to think something like $10K for Altium was a borderline crime. Now I sell robots for the same amount. (And people in the industry still say I'm charging too little.) Long story long, if you think $10K is too much for something, you're not their target market. (And as long as there are viable open-source alternatives, I don't have a problem with that.)
