i think you should make it paid version but with low cost let's say $30-50 and with the huge list of users this small amount of money will make a good fund for ZAP developing . So with this solution it solve both side problem . The user can't afford other web scanner like burp or caido but can pay $30-50 per year for ZAP and the ZAP team could use this money to support ZAP developing in a win-win situation

People would only pay if we made ZAP closed source.. which we don't want to do..

For commercial support options see
ZAP is supported by the Crash Override Open Source Fellowship

Thats kind of the idea :)
But if ZAP uses an OSI license then there's no incentive or requirement for companies that use ZAP heavily to support ZAP in any way.
There are several companies who have build their entire businesses around ZAP, and they do not support us.

That is why we are looking at non-OSI licences - therse companies will then have to make a choice:
  • Pay a license for the new version of ZAP we maintain
  • Maintain ZAP themselves
  • Stick with the "old" unmaintained version of ZAP
  • Drop ZAP entirely from their offerings
