 + We have strong reasons to believe including the Cask can put the whole project at risk. Happened only once so far, [with Popcorn Time](https://github.com/caskroom/homebrew-cask/pull/3954).
 + The cask is so difficult to maintain, it constantly breaks. Happened only once so far, [with Audacity](https://github.com/caskroom/homebrew-cask/pull/27517), because it uses [fosshub](https://www.fosshub.com/faq.html) as a distribution site.
-+ The app is a trial version, and the only way to acquire the full version is through the Mac App Store ([documented](../development/adding_a_cask.md#trial-and-freemium-versions)).
++ The app is a trial version, and the only way to acquire the full version is through the Mac App Store.
   + Similarly (and trickier to spot), the app has moved to the Mac App Store but still provides old versions via direct download. We reject these in all official repos so users don’t get stuck using an old version, wrongly thinking they’re using the most up-to-date one (which, amongst other things, might be a security risk).
 + The app is both open-source and CLI-only (i.e. it only uses the `binary` artifact). In that case, and [in the spirit of deduplication](https://github.com/caskroom/homebrew-cask/issues/15603), submit it first to [Homebrew/core](https://github.com/Homebrew/homebrew-core). If it is rejected there, you may then try again in Homebrew-Cask (link us to the issue on Homebrew so we can see their reasoning for rejection).
 + The app is open-source and has a GUI but no compiled versions (or only old ones) are provided. It’s better to have them in [Homebrew](https://github.com/Homebrew/homebrew) so users don’t get perpetually outdated versions. See [`gedit`](https://github.com/caskroom/homebrew-cask/pull/23360) for example.
