Per the article, Japan reduced its Southern Ocean whaling in response to the International Court of Justice, not the Sea Shepherd.
Protesting in an international forum is fundamentally different from protesting domestically. There is no coërcive third party to enforce the rules. You have to convince the people you're protesting to want to change. Contrast the culture at the UN to e.g. a regulatory agency.
Most Japanese don't eat whale [2]. Whaling has become a symbol of national sovereignty and pride. Foreign vessels ramming your ships stokes national pride. The Sea Shepherd Conservation Society may have eliminated a diplomatic solution to whaling for a generation or two.

Private entities are allowed to enforce the law in international waters, actually.
In any case, what law are the Japanese vessels breaking? They amended their quotas to comply with the ICJ ruling [2].
Ramming things makes for good TV. It is emotionally satisfying. Practically, however, it is ineffective or even detrimental towards the goal of saving whales. (It is very effective at maintaining certain peoples’ livelihoods and drumming up nationalistic support for whaling in Japan.)

Diplomacy is apathy by committee. If governments do not act, private citizens must. We only get one Earth.
In most countries, the right of private citizens to enforce the law themselves is very narrow. This is not because we do not respect the law, but because allowing private people to play cops and robbers can easily become a situation where it’s hard to tell who is what.
If so, that’s unfortunate, as violence is sometimes necessary against a bully. If not, what’s the difference?
