Translation: one of Mullvad’s two cofounders has donated money to Örebropartiet, a left-leaning Swedish political party that promotes strict and restrictive immigration laws.
There's no such thing as a left-leaning party that harsh on immigration. Only parties that call themselves left-leaning. You may as well speak of a capitalist party that wants to seize and redistribute the means of production.
And “donated money” here means “his donations amounted to 72% of the party's entire 2025 revenue”[0].
