Because it has been proven false time and time again. Mozilla checked ProtonVPN by meeting with the team in Geneva. The EU also checked Proton Technologies extensively before granting 2 million euros.
Proton Technologies does not outsource. It has offices outside of Switzerland in Czechia, Macedonia, and Lithuania, but the bulk of the staff is in Switzerland. There are team photos online (https://www.instagram.com/p/BuWTJlaHPOf/), and if you visit the address on the website, you will see it is indeed that building.
On the other hand, there is ample evidence that there are shady VPN companies engaged in a large scale disinformation campaign against ProtonVPN. Just have a look at the 500 Twitter bots used to spread the rumors: https://twitter.com/conspirator0/status/1036353291662360577
So who do you want to believe? 500 bots on Twitter, or Mozilla, the EU, and the state of Geneva who have all come out and verified the company?
If ProtonMail had grown like a typical Swiss company, only hiring candidates from Switzerland, we never would have been able to find enough talent to drive our growth. By hiring globally, and disregarding which country a candidate is from, we increased our potential hiring pool from 8 million to 7 billion. A diverse workplace also helps to attract applicants. More applicants means we can hire more candidates, while simultaneously being more selective.
But I'm glad that EU money is spent for hiring globally.
