We (my company) have filed quite a few radar bug reports, including one quite serious flaw (account passwords being sent across a network in plaintext serious). We never heard a squeak back. We never know if they have, or will ever be fixed in a future release.

Some of these bugs affect our software critically, but we're completely in the dark about whether we should invest serious time and energy into providing our own workaround or leave it as it'll be fixed in the next Mountain Lion Preview.

This lack of communication is one of the worst things about being an Apple developer, and I fully support the community's efforts to try and persuade them to do better.
