One point, Google regularly makes false announcements about unpopular changes. When they changed search results to better hide which ones are ads they announced they’d backtrack on it, then didn’t. When they started hiding parts of the URL they backtracked on it, waited a few months, then re-implemented it. When they decided “don’t be evil” isn’t really appropriate for them any more they said it’d only apply to Alphabet not Google, then waited a few months, then applied it to Google.
