It depends where you live. In Eretz Yisrael or Boro Park, it’s hard NOT to find chalav yisrael products.
I once had a chavrusa who had a tayva for Entemann’s Cookies, which aren’t chalav yisrael. So he was mareh heter for himself.
In many communities outside of Brooklyn, it’s hard to find chalav yisrael. So I could understand people being maikel there.
