This is from yesterday's Brazil - Taxation panel report:
7.565. In reviewing the arguments and evidence submitted by Brazil, the Panel considers that Brazil has demonstrated that there is a problem of a "digital divide" in Brazil, and that the problem of the digital divide has implications for people's standards of living. As noted by Brazil, the Preamble to the WTO Agreement explicitly states that the WTO Members "[r]ecogniz[e] that their relations in the field of trade and economic endeavour should be conducted with a view to raising standards of living". The Panel highlights that this concern is internationally recognised as an issue confronting developing countries. Furthermore, and taking into account that Brazil has indicated that access to information and bridging the digital divide have an educational component, the Panel recalls the panel's statement in EC – Seal Products, in a finding that was not appealed, that "WTO Members are afforded a certain degree of discretion in defining the scope of 'public morals' with respect to various values prevailing in their societies at a given time." Although this "degree of discretion" is not boundless, in light of the above the Panel is inclined to defer to Brazil.

7.568. The Panel therefore finds that Brazil has demonstrated that a concern exists in Brazilian society with respect to the need to bridge the digital divide and promote social inclusion, and that such concern is within the scope of "public morals" as defined and applied by Brazil.
That seems like a lot of deference to respondents on what constitutes "public morals." If this is in, couldn't just about any policy be fit in there somehow? Obviously, there are other elements to the Article XX standard, but still, that's a broad finding.
