(Telecompaper) EU member states are unlikely to support a ban on zero rating, according to a proposal on net neutrality by EU president Latvia, seen by Reuters. Zero rating means operators offer unlimited access to certain online services, such as Facebook, music streaming or online TV, without additional data charges. The proposal from Latvia says that an explicit ban on positive price discrimination - such as zero-rating - was unlikely to gain the support of all members. "The issue of positive price discrimination could be left outside the scope of this instrument...this would allow each member state to decide whether to ban price discrimination at national level, or leave the assessment of such practices to general competition law," the document says. Countries such as the Netherlands and Norway already have bans on price discrimination. Member state representatives will discuss the Latvian proposal 27 January.
