When you come to a new open source project for the first time to report an issue, a "thank you for your work" or any kind words are very welcome.
We give our free time to contribute. We have no salary and we represent no company. We are humans who want to offer the best for everyone.
Yes, issues are mostly opened when something is wrong, but before writing one, remember the dev will read it and try to help you. We are not a company selling your data, and you did not pay for a service.
