Seems fair to me, they're a nonprofit that exists in our lived reality and not an abusive monopolist that can literally throw a billion dollars to subsidize loss leaders.
All it shows the world is why there needs to be a VAT like tax against US digital services to help drive a public option for developers.
There's no reason why the people can't make our own solutions rather than be confined to abusive private US tech platforms.
Adding taxes to things does not help anyone and goes against free choice.
A better alternative would be to create the incentives so that companies like these can be born in Europe.
Companies like Microsoft should not be given "incentives to exist" anywhere (at least as they exist currently). They are corrosive to the public good.
