You all need a bit of clarification on a number of points.
1) OU-D does NOT mean it is dairy. OU has no Parve but made on “Dairy Equipment”. OU-D means it may have milk products or it simply may be parve but was made on dairy equipment. Unfortunately, the only way to tell the difference is to read the ingredients.
2)HaRav Moshe Feinstein was America’s greatest posek and gadol hador. He paskened for the United States and Canada on many complex and major halachic issues that dwarf the issue of cholov yisroel. Believe me, even HaRav Eliyashiv and ZTL HaRav Shlomo zalman Auerbach considered HaRav Moshe as a truly great and equal posek and even when they disagreed with him, they agreed that he paskens for America and they pasken for Eretz Yisroel and Americans should listen to his psak. If you can rely on HaRav Moshe’s psak in severely complex issues, he can be relied upon for less chomur issues.
3) HaRav Moshe paskened that “Yediyah is K’Rieyah”. The absolute knowledge that milk has to be Kosher in that it has come solely from cows, is halachically equal to seeing the milk being milked directly. In other words, what people call cholov stam is actually according to the psak of HaRav Moshe actually halachically cholov yisroel as Yediyah k’rieyah. HaRav Moshe held that for chinuch purposes, schools, institutions and families when able, should use cholov yisroel in order for children to know that outside of the United States hashgacha on milk is an absolute requirement.
4) No one claims that cholov akum is kosher.
5) It is very easy for anyone to claim additional chumros and be mivatel what they perceive as kulos. Chazal come out harshly against those who behave this way as it destroys Kllal Yisroel as not all can withstand endless chumros. It makes Hashem’s Torah unpalatable to the rabim and creates machlokes and sinah. Never ever should someone even suggest to impugn the psak or character of HaRav Moshe Feinstein, a posek of a caliber that one sees if fortunate, once in a lifetime.
