This "report" is exactly what I would expect from Lunduke. It is really sad that this reactionary content comes from someone who I once thought was cool.
The only part I can agree on : the execs at Mozilla are getting paid too much in the current situation.
Now to get to the real meat.
The combined spendings to political organizations make up around 1m$. This is less than the donations made to Mozilla foundation. Considering the very political nature of the foundation, these spendings were likely authorized there.
Now, why would a technology company spend on political organisations? Well, simply put : technology is political. People trying to peddle that technology is not political are trying to sell you the status quo.
Technology companies spend insane amounts of money on lobbying.
Now, why would Mozilla spend money on left-leaning organisations? Well, simply put : left-leaning politics (though embedded in neoliberal Californian ideals of the internet) are embedded at the core of Mozilla from the start with Mozilla manifesto.
I'm not gonna get into why Lunduke thinks that these organisations are bad but consider it a red flag.
Now, what I would ask to anyone reading this : why do you think Lunduke is ignoring this? Why would Lunduke try to paint this picture?
