to the internet's margin

Dear all,

What does Jacobins refer to?

How should I understand "to the internet's margins" underlined below?

Thanks in advance.

Nor should a government fear to act because its adversaries are popular and fight back. That the digital Jacobins of WikiLeaks have a cult following should not save them from condemnation or prosecution. Removing illicit material from the internet is hard. But governments spend a lot of money, rightly, on chasing child pornography, bomb-making techniques and copyright breaches to the internet’s margins. Similarly, discouraging WikiLeaks and those who give it financial and technical support (see article) is justified for elected politicians in a law-governed state.
