+## Diagnostics Missing In Issue
+
+You have filed an issue against the card, but failed to include the required
+diagnostics and/or missed this warning in the new issue template:
+
+```
+<!-- =================================================================
+***               PLEASE DO NOT IGNORE THIS TEMPLATE
+***
+*** This is the smallest amount of information needed to help you!
+====================================================================== -->
+```
+
+Without the diagnostic data, it is substantially more time consuming to try to
+"guess" the basic parameters necessary to help you. I _really_ want this card to
+incrementally improve, and I think time is better spent working on reproducible
+issues or new features, than guessing what versions/options you are using. The
+new issue template asks for the minimum possible information to support you:
+
+- **Diagnostics**: On the card, hold down the Default/Frigate menu button for a
+  few seconds then paste the diagnostics into the issue between the backticks.
+- **Description of the problem**: I need to understand the issue in sufficient
+  detail.
+
+This seems like a reasonably low bar for help, so if your issue gets closed for
+not providing this information, please do not be offended. I want to help, just
+need to prioritize my limited development time well. Feel free to re-open your
+issue, providing the requested information.
+
+## Misconceptions About open source
+
+- The fixes aren't fast enough!
+- The features aren't good enough!
+- The quality control / testing is not sufficient!
+- There are too many / too few releases!
+- It breaks too frequently!
+- This just isn't good enough!
+- My tone is disrespectful!
+
+This is the joy of open source. A sense of entitlement regarding when/how soon
+fixes should be provided, or new features developed, is misunderstanding the
+fundamental dynamics of open source. I am sorry you feel this way, but open
+source software (including this card) is typically provided "as-is". Take it or
+leave it. If you want things to go faster / differently, [please
+contribute](https://github.com/dermotduffy/frigate-hass-card/issues/1248). If
+you don't want to contribute to the shared codebase, fork it and make your own.
+Or pay for a (different) Enterprise grade solution to your problem. This is
+certainly not that -- a card, developed in hobbiest-level time, with
+hobbiest-level skills and ... at best ... hobbiest level support.
+
+If you find yourself complaining, your expectations are incorrect! This is
+undoubtedly frustrating (and I have often shared in this frustration), but it is
+nonetheless just "the way open source is".
+
+Thank you for understanding!
