I'm the main contributor of an app that emulates Windows's alt-tab feature on macOS (<a href="https://github.com/lwouis/alt-tab-macos" rel="nofollow">https://github.com/lwouis/alt-tab-macos</a>). I researched this topic extensively, and eventually decided that I would bite the bullet and pay from my own pocket, so that users get a good UX when launching the app.<p>It is displeasing to see Apple not having an open-source program in-which they give free certificates for popular open-source projects after a review. They are a large beneficiary of OSS after all.<p>Furthermore, smaller companies do it frequently these days: Jetbrains gave me free IDE licenses, poeditor gave me a free account, github hosts the project code, ticketing system, and is the distribution channel for first downloads and updates, appcenter hosts crash reports for free, travis does the CI for free, etc.
