There’s a famous “Berdichever” story. Once the Berdichever Rebbe saw some frum wagon drivers greasing the wheels of their wagons as they finished up Shachris. The Berdichever said “Look at the greatness of Klal Yisroel — even while greasing their wagon wheels they are davening!”
Seriously, everyone has their own nisayonos, and for some waking up on time is very difficult. It is their avodah, and quite frankly none of your business. Can you say in honesty that there are not areas of Halacha that are hard for you? When people speak Loshon Hara, is that always “an open disregard for the halachos of shmiras halashon”? I would venture to say that for most frum Jews it is an issue of overcoming a particular yetzer hara, not disregarding Halacha.
