This only supports my point about having more stuff to maintain. Now there's this GitHub page having a large "Download on Flathub" link that goes absolutely nowhere because the package is unmaintained. Who makes the GitHub page go away?

https://github.com/flathub/com.whitemagicsoftware.kmcaster?t...

Also, the image on that page is outdated, which would have been one more thing to maintain. In addition, the install instructions are four lines of code to run, compared with three lines of code to download without Flathub. My point stands: Flathub adds an unnecessary maintenance burden (to some projects).
