That's what he said, you aren't applying this change to your paying customers because you know what a shitty decision it is and only free users will put up with it.
free users get the same value as paying customers...JetBrains can do as they please to get some value out of these users. Don't like it, pay up...I'm a long time JetBrains customer (since 2005). I've never asked my employer to pay for my licenses because their tools make me a better developer than any other options on the market.
