Ok, it's a very good add-on, supplies some needed functionality. So much so I decided to look at paying for the pro license, just to support the developer.

But then, I got to the licensing page, and saw the part where you can't buy it, only rent it for a year. Then, even though you haven't consumed any more of the developer's resources by using it on your onwn computer, you have to pay him for it again. And again the next year. And again the next year.

Sorry, that's not how it works. If I buy something from you, I'm buying it from you. You don't get to take it back every year just because you want to charge me again and again for something I already paid you for.

Write software that's worth paying for (which you definitely have), and people like me will happily pay a fair price to buy it. Once. Then, if you release a new version with better features, we'll happily pay an upgrade fee for that.

But expecting people to pay over and over again for the same thing just because you wish to make unlimited money off of them is just greedy. I won't support it. Once I've paid you for something, it's mine. I get to use it. You don't get to say how long I can use it for.

Otherwise, you don't get to have me as a customer for your product.

Please reconsider your licensing model. Best of luck to you.

thanks for your feedback. A couple of things to not:

Would it help you if it was permananet but fixed to just Thunderbird 78 as maximum version? Because I have to rewrite my Add-ons every year to future proof them. This is different from Software that is compiled to run on an operating system which is guaranteed to stay stable for 10s of years. Every year the ESR comes along and breaks a lot of things. If I sell a permanent license this i a broken promise: I walk away and do nothing and it will stop working after a year - or you are forced to stay behind on an outdated Thunderbird version.

So you are not paying me for the same thing but for the fact that I am not walking away and keep fixing and re-writing the code. Last year I had to invest 3500$ by hiring an external developer just so my Add-ons could survive - plus putting in many weeks of my own work.

Once we have converted the Add-ons to full blown web-extensions which work with the Thunderbird APIs only I will definitely sell permanent licenses but it's a long way until then. The APIs are incomplete and do not allow many things that were possible with legacy Add-ons (and are currently possible with experimental add-ons of which quickFilters had to become one.
