1- Lets's say I am a freelancer and I have bought a 3rd party module for one of my customers but luckily I have another customer that can use this module can I share it without buying again or do I have to buy again and in this case how to ensure that customer has some kind of prove that he has paid for his module
2- Another situation is I bought a module of version 12 now it's not available in Odoo 13 so I converted the module in 13 can I share with the new customer
3- Some modules are very expensive to be bought before testing and customer want to test with there local database that they will not share it with 3rd party members and wants to make sure how they look in the enterprise, if we bought a module and it's not working as the explained on call or email can we complain about them to get a refund or just accept the loss because many time customer backs off just to avoid this risk
I am trying to figure this out in term of ethical and moral values,
and yes there are some 3rd party paid modules with no licence or incomplete info regarding this matter.
