For tuned, I don't need the bug fixed, as I simply don't want it changing any kernel settings at all. Uninstalling it achieves the result that I want.

The rest of the rant is valid and the issues are virtually impossible to get fixed.

Please enlighten me: how does one file a bug against spam filtering on gmail.com or get rid of broken AI summaries on google.com that will garner an acknowledgement and get the underlying issue fixed?
