Your analogy is off. CurrentC is not making merchants agree to disallow Apply Pay. The merchants have simply chosen not to accept Apple pay.
Yes they are. Part of the agreement is that they cannot accept any other mobile wallet
But isn't an "exclusivity" agreement with no substantive repercussions for violating it meaningless? According to the front page Macrumors post, "Merchant Customer Exchange (MCX) held a conference call with members of the press to further address questions and concerns. During the call, MCX CEO Dekkers Davidson and COO Scott Rankin clarified that MCX merchants who choose to accept Apple Pay are not subject to fines. As stated in the blog post earlier today, merchants are also free to leave the consortium entirely at any time without penalty beyond forfeiting the time and money already invested in the effort."
