Why does Orbán concentrate so much in fighting some NGOs?

Question

Recently, George Soros Group has left Hungary:

Citing "an increasingly repressive political and legal environment" in Hungary, the OSF said in a statement that its decision to quit the country comes amid a crackdown on non-governmental organizations launched by Prime Minister Viktor Orbán, who won re-election to his fourth term in a landslide victory last month.

Orban's party has managed to secure a super-majority for the third time in a row, so it has a great power at all political levels (e.g. this allows even to change the Constitution):

Hungary’s Civic Alliance (Fidesz), led by the prime minister, Viktor Orbán, and his junior coalition partner, the Christian Democratic Peoples’ Party (KDNP), has decisively won a third super-majority in the country’s national election.

Previous wins in 2010 and 2014 have enabled Orbán to radically change the Hungarian constitution. He rolled back democratic checks and balances to build what he described as an “illiberal democracy”. This latest victory for Fidesz will serve to consolidate this shift away from the European liberal political mainstream. Orbán is now firmly entrenched as a major political thorn in the side of the EU and a champion of populist politics for the continent’s right wing.

Considering above, I am wondering why invest so much effort evicting some NGOs, when there is virtually no significant opposition.

Question: Why does Orbán concentrate so much in fighting some NGOs?

Answer 1

Orbán believes that they are a significant opposition:

The Prime Minister has accused [Soros] of meddling in the international affairs of countries and trying to flood the EU and Hungary with migrants.

This ties into antisemitic conspiracy theories:

From Russia to the United States, the currently ascendant nationalist right has transformed Soros from a human being into a synecdoche for a shadowy, powerful cabal bent on transforming Western countries into something alien and unrecognizable—a rhetorical maneuver conspicuous in hundreds of years of European anti-Semitism.

While Orbán has all the political power, he can still be afraid of a shadowy group of people who are secretly manipulating events to increase immigration and thus destroy the Hungarian government, bring down its "Christian culture", and turn Europe into a "mixed population". These are classic antisemitic themes which are not necessarily open to reason or facts (eg Orbán actually having all the political power).

Answer 2

It probably have to do with the election. Orbán paints himself and his party as an underdog fighting against "the elite", but when you have almost full control of the country it's a bit hard to do that so he had to invent an enemy and George Soros is vary convenient as Orbán then also can tie the campaign to anti-Semitism.

Answer 3

Because

1. Some NGOs promote policies that directly contradict political platforms of some governments. Specifically, Soros and anyone he funds tend to be radically "left" (or rather, progressive to be more precise), and push for policies directly opposite those desired by the "right".

   Very specifically. Soros's NGOs are heavily pro-unrestricted immigration, which is in polar opposition to many right wing parties (which has little to do with Orban or Hungary per se, as Soros is also opposed by even mainstream right wing parties from US's Republicans to Israel's Likud and Israel Betienu).

2. Some NGOs are extremely powerful and capable, with resources and influence on par with governments.

   Specifically, Soros' funded NGOs have thousands of people, virtually unlimited funds supplied by Soros (who's a finance billionaire) and enormous influence.

   Here's a hungarian article about Soros' NGO (I assume it's a pro-Orban source, but any claims in it can be verified)

   According to a recently uncovered statement by Tracie Ahern, former chief financial officer of the Soros Fund Management, the billionaire financier commands a quasi-mercenary force of at least 2,000 people, tasked with achieving three goals: bringing down Prime Minister Orbán’s government, dismantling the border fence, and promoting immigration to Hungary.

   The statement marked the latest in a series of revelations of Soros-funded efforts that attempt to influence public life in Hungary and oppose the work of the democratically elected government. Earlier this month, the Jerusalem Post broke a story about how a Soros-funded NGO in Berlin, headed by a Hungarian national, is actively lobbying the German government to apply pressure on Hungary to change laws on NGO transparency. A few weeks ago, I posted on a Hungarian media report about an astonishing revelation that George Soros spent more than 14 million USD in 2017 lobbying the US government against Hungary. We’ve also called attention repeatedly to his Open Society network’s lobbying efforts in Brussels (here and here). Hungarian media also reported on a Soros-funded NGO illegally collecting data on migrants.
