Conflict between Brahmajala Sutta and current Buddhist practices

I'm very confused about this sutta ( http://suttacentral.net/en/dn1) specially in the part "Mahāsīla" Many of what the Buddha stated as wrong livelihood is very common in some Buddhist centres these days, things like: Astrology, selling lucky gems, offerings to deities etc... if you read the list in the sutta you will see it. Is this sutta not part of some Buddhist cultures? Am I interpreting it in the wrong way? Or is it simply being ignored??
