“To take a common example, can someone who is bittul zman not advocate that people not be bitul zman or at least do so less?”
Joseph,
You have made a very important observation about yourself so please contemplate my comment and don’t lash out defensively. When proper leaders with the mandate to rebuke others exercise it, they do so only when necessary, they first include themselves in the criticism and they then discuss how everyone can improve. You are not a Rav and not a Rebbi so your mandate to rebuke others is non-existent. Yet somehow you have turned a twisted view of Hocheiach Tochiach into your only purpose in life. You waste countless hours on this site incessantly criticizing entire groups of Jews on every imagined shortcoming, yet you never admit to having those very faults yourself.
To answer your question: no; one who engages in bittul zman, uses unreliable hechsheirim and embezzles cannot criticize others for doing so because that’s the epitome of hypocrisy and also the very definition of a troll. Hocheiach Tochiach is not the primary objective of any sane person. Criticism should generally be directed inward for the purpose of self-improvement. When a person occasionally admits to their own faults, expresses remorse and gently shares with others how they were able to improve, that’s a mitzvah. Constantly beating up others because of one’s own flaws is the opposite of a mitzvah
