Posting this because I hadn't heard about it before and I'm probably not the only Mullvad user here, so might as well.
The party claims to stand for a "class-conscious populism" which according to party leader Markus Allard takes inspiration from marxist ideology and unites the "productive" classes of society against the "Transferiat", with the "Transferiat" being a term coined by Allard to describe the classes of society that lives off transfers that are a net negative for society such as those who, despite having an ability to work, live off social welfare benefits, as well as those who work "made-up services"[...]
The party differs from modern day left-wing parties by seeing the working class as co-dependent with people working in enterprise and business and instead sees the classes that "live off transfers", as specified, as a large economic net-negative and an obstacle for a functional society.
Their ideology is nonsense fake-marxist revisionism to redirect anger at capitalism and turn it against immigrants and people who need social welfare (though they do back some generally left oriented social policies, their main thing appears to be racism)
Even if you're comfortable with funding this, it still begs the question of just how trustworthy Mullvad actually is.
I guess this still beats any of the dozens of Israeli VPNs that definitely spy on you, but it's not great 
If it actually matters then you should stick with mullvad. Like, if you’re concerned about being attacked or punished by government or something.
If you just wanna watch porno at work and prefer anonymity, ivpn is a cost effective alternative that can be used in the same way as mullvad if you’re careful and know what you’re doing.
If you just wanna download files and are not Italian then air is a good cheap port forwarding vpn.
