Yep. Donation based systems are quite broken. A number of years back, I wrote a small utility app for typing Hanyu Pinyin with tone marks (https://www.pinyinput.net https://www.pinyinput.net) that I made available for free, with a 'Donate' button and exhortations that people could donate if they found it useful. Despite 10s of thousands of downloads over a period of about 5-6 years, I could count on two hands the number of donations I got. Then I changed it to pay what you want (including $0) with a default price of $5. And you click a purchase button rather than a download button. Plenty of people still download it for free, but now it also gets a payment every day or so - sometimes $1, sometimes $5, sometimes more, but it's a consistent trickle.
