However, given the fact that it has been abandonware for a long time now, I did look for alternatives for that fateful day when Apple fucks up macOS sufficiently where Skitch is no longer executable, which is not a question of if, but a matter of when.
I decided that CleanShot X was the closest thing to a suitable alternative to Skitch, although it has a number of really annoying design decisions that keep it from being a suitable replacement for Skitch, unfortunately.
If someone could convince the owners of the Skitch IP to open source it, I would be very interested in helping maintain it.

> Just as before, Enterprises using the ExtensionManifestV2Availability policy will continue to be exempt from any browser changes until at least June 2025. Starting in June, the branch for Chrome 139 will begin, in which support for Manifest V2 extensions will be removed from Chrome. Unlike the previous changes to disable Manifest V2 extensions which gradually rolled out to users, this change will impact all users on Chrome 139 at once. As a result, Chrome 138 is the final version of Chrome to support Manifest V2 extensions (when paired with the ExtensionManifestV2Availability key). You can find the release information about Chrome 138 and 139, include ChromeOS's LTS support, on the Chromium release schedule
