This is very confusing to me. I have been told cholov stam is not cholov treif. And I have read frum articles stating it is possible the origins of cholov yisrael were controversial, if not motivated for a share in the marketplace. I find it curious that someone may be halachically bound to CY once they prefer to buy CY either for convenience of they feel it is on a higher level.
Based on what I am reading here, can’t one argue that if one buys any food of a highly credible hechsher three times that they can not halachically go back to a hechsher less reputable?
And let me ask this: Should I continue mixing CS with CY because once I go all CY, I cannot go back without problems??
Also, let me throw this out there: I was told the longer ones tzit tzis are, the better. So if someone wants to go to a shorter length, closer to a 16, so it is not so bulky under certain shirts, is that the same kind of problem?
