I’m not sure who you’re using as your test case, but all of us have observed multiple Chassidishe communities and found what you’re saying not to be the case. I’ll let you in on another secret: 10 o’clock shachris is not the norm for chassidim. Only Chabad, and maybe some neo-chassidic types who like to sleep in after partying the night before. And, it should be said that true Chabadniks are careful to say the shema b’zman.
We aren’t accusing you of lying. It sounds like you’re just making inferences from a group that does not represent anything close to the norm.
