Selling actual software licenses again that don't require connecting to a remote server to use? Like the had for over a decade. They could still do point release updates on-line, but the software itself should come with a license key that just works without needing to validate over the Internet. Even if they didn't want to do that, they could do the Jetbrains perpetual fall-back license model where if you hold a license for version x for a year, you get to keep version x. You still get version y when it comes out, but if you cancel before a certain time, it will fall back to your license for x forever, until you pay your subscription again.
