Everybody has their limits of patience. When it comes to charity, you shouldn't annoy donors. It takes a microscopic amount of time for me to close their tab and forget about them. So fuck them.
I get what you are saying, but I think a more charitable interpretation is warranted.
He's saying he asked for a feature, they asked for money, he offered a little money and they said it wasn't enough so he balked.
We can agree on that much, right?
I think, and this is my assumption, that he wasn't expecting the rustdesk devs to come running and immediately roll out his suggestion for his generous $18.
I think he just wanted to put the suggestion onto the pile for consideration, and then when rebuffed for another $2 decided that if he can't even make a suggestion for $18 then it's not worth $20.
Then he went on to complain that they wouldn't even put his concern on the pile for less than $20 and now he's getting (imo unfairly) dragged for it.
This is my interpretation of the events. I might be wrong but I don't think I am.
There is little expectation of return, the way they present it. Contrast that to actually purchasing software, where they are required by law to deliver what you pay for or give your money back.
