No you are not under any obligation to post anything, however when posting something you claim to be a violation of law or policy is customary to support that claim with citations to where you have gained this knowledge. To date you have not posted any citation to support your claim in a verifiable manner. You have posted no terms, no laws, given no citations of any regulations or policies that are open to the public review, My own investigations have found nothing in any written documentation to support your claims. I believe you are wrong, and have asked you to provide a citation back your claims, which to date you have not.
If this was an official position of either Visa, MC, or an "IPSP" you would be able to post a link to their official terms that spell out that position, since you can not your comment should be ignored.
As to PCI Compliance, I will say again, ALL PERSONS TAKING CREDIT CARD MUST BE PCI COMPLAINT. Small, medium, large it does not matter, if you accept credit cards at all you much be PCI Compliant. Level 4 Compliance is a joke, and even the smallest of small business can become Level 4 Complaint...
Level 1, which is what a Walmart would be, is hard to get and most online merchants do not even attempt to get that.
