I didn't understand what was going on, so I asked AI for an explanation:

Mullvad co-founder Daniel Berntsson personally gave SEK 5 million to Örebropartiet, a Swedish populist party with a hardline immigration platform, and customers revolted when it came out in June. theregister

His post defends the donation: he dislikes most of the party’s policies but thinks it alone is addressing Sweden’s dependence on tax-funded transfers. dberntsson

Tor’s post is the fallout, since it co-develops Mullvad Browser with Mullvad’s funding. It is keeping the technical collaboration but pausing co-branding and removing language that implied shared values. torproject

Here's the founder's explanation: https://dberntsson.info/
