Double down efforts to survey users and potential users. Keep making the product better. Consider the pirate option as a competitor. Don’t demonize your user base, but don’t be afraid to go after any institution you know is using pirated version. Build multiple telemetry code paths in your code — if you can just get IP addresses of offenders you’ll have way more info than now.
Sorry, but from where I stand that absolutely looks like demonizing the user base.
