WARSAW — Prime Minister Viktor Orban of Hungary said on Friday that his government would abandon, at least for now, a proposed tax on Internet usage that drew tens of thousands of demonstrators to the streets this week.

“We are not communists, we don’t govern against the people,” Mr. Orban said in his regular weekly interview on Hungarian radio. “We govern together with the people. So this tax, in this form, cannot be introduced.”

Ebullient protest organizers — who had charged that the proposed tax was an attempt by Mr. Orban’s right-wing government to choke off one of the last sources of information not controlled by him and his allies — called for victory celebrations across the country.

“After long years, Viktor Orban has recognized that he doesn’t represent the point of view of the majority on an issue, and has admitted that the majority of the people rejected this tax,” said Balazs Gulyas, 27, a former member of the Hungarian Socialist Party who set up a Facebook page last week that inspired the protests.
