Maybe “You get what you pay for” is more appropriate.

You invested (your time, energy, reputation) into a system which you either knew or could have quickly established, places no value in you as a person and has zero interest in fixing any problems that may affect you. I'm sure many users started using it for nothing of any real importance at first, so didn't let that really worry them. But over time, they invested much more while still in the back of their mind knowing that while the odds are small of anything happening, that if it did, your data and relationships could be taken from you, and possibly even given to others, for reasons you may never even know, or reasons you may know to be false but unable to do anything about the error.
