(probably this can be commented by more qualified people than myself)
TL;DR
Chile's government (Subsecretaria de Telecomunicaciones, SUBTEL) has
issued a circular (i.e. an explanation of the law), called circular n.
40[1], earlier in April this year stating that zero-rating go against
the Chilean net neutrality law in force (spec. disposition n. 6 and 7.
of law n. 18.168)[*]. Today SUBTEL has "confirmed to us [WMF and
Wikimedia Chile] that the new order was not intended to prevent
Wikipedia Zero and similar free knowledge initiatives"

Well, in one word this is, for sure, "a thing".
