Who changed nussach hatefila?
Fwiu often shiur starts right after davening, whether it's a short halacha, mishayis, or a sif chofetz chaim, isn't that terrible as well? To change davening like that?
This reminds me of the gadol that said at least they are adding rosh hashanas not taking away.

You need a serious serious Chesbon nefesh this Y"K, if you get disturbed by other jews saying more tehillim. There is clearly something wrong with your outlook on Judaism and life in general.
The issue is precisely the fact that chabbad tried/did institute this as a fundamental part of Seder tefilas shachris.
It has nothing to do with sinas chinam, or anything against anyone saying Tehilim all day long.
It is about having the authority to change Seder hatefila.
This is a sacred thing that shouldn't be adjusted on a whim. It is not just done in modern times.
I've said enough to present the opposing views... Still love y'all.
