We need to pay more for software, not less. The Freemium model is killing products because you can't make any money from writing programs anymore unless you get a huge homerun. People only want to pay $0.99 for a program that took months of man-hours to write. $5.99? Fuck it, that's too expensive!
IntelliJ is magic to me. It's a wonderful piece of software, and I generally do not like Java. But it has transformed the entire experience.
Companies like JetBrains needs to be incentivized to write this kind of software, and innovate on it. They're not going to if they have leeches that use the free version in perpetuity. And if they change to a subscription model, then good for them.
If you use IntelliJ in a professional context, and you make a decent wage, a large part of it is because of IntelliJ, so you should pay up. $200/year is nothing compared to other things people spend money on like Starbucks, DirecTV, gas, etc.
