You're absolutely right that businesses act within whatever constraints exist — and yes, we were a bit naive. We assumed that if someone had a fully functional, free, open source version available (well-documented and easy to install), nobody sane would go out of their way to abuse the trial system instead.
To be clear, it’s not just trial abuse — it’s actively ignoring the better, freer option in favor of repeatedly faking evaluations just to get the “easy mode.”
We’ll definitely tighten things up going forward. But in nearly a decade of doing this, they're the only ones to push it to this scale. So yeah, they've earned a spot in our open source hall of shame
Ignoring an OSS option is not the crux of the issue, it only adds more stupid to the cake. They don't deserve a place on the OSS hall of shame, but on the list of shysters and fraudsters.
A company is exploiting your free-trial offer, defrauding your project of resources even if it is only a buck and a half. Why are you sending them money? Just shut them down. Unless you have some really unfortunate wording in your TOS, there is nothing they can do. On Monday, send an e-mail to all accounts associated with $COMPANY and tell them in clear terms that you are going to terminate their free-trials COB EOW. Leave a special contact number to negotiate fees, wait for your phone to ring.
Seriously, why are you putting up with this?
To be fair to them - they've been doing it for 10 years without a problem!
Yes. Your pain point is the level of support you are giving on good faith to these charlatans. Maybe add a clause to your license that you reserve the right to limit the amount of technical assistance on the free download. Outside of that, if I understand this matter correctly, most of your customers are honest and you’re willing to write off this one company in the interest of keeping your own corporate sanity.
