I am fully aware of what vpn services to use and not. I am not using Express VPN, I am simply doing research for a master thesis, when I came across these results from Express VPN. If you have any ideas or corrections, please let me know why a VPN provider would need to have access to these permissions.

I prefer mullvad. Not only is their pricing and account system much more privacy focused, they are a European (Swedish) company and are bound by the laws of my country by default. Another European one is surfshark (Dutch) which I used before. I trust mullvad more though. They also have open source clients and had no user data stored when they were raided once before.
Edit: clarifying the reason I used surfshark. I used it back when I was in high school a few years ago, so their 3 year plan seemed like a very good price. They also supported this very obscure VPN protocol whose name I can't remember, and my school just so happened to have forgotten to block it on their network. But I couldn't use that protocol on Linux due to incomplete connection steps provided by surfshark, and I switched to using linux full time in the second half of my first year, so that was a waste and I just used my mobile data.
They also push the envelope on privacy, and frequently publish security reports.
not to discredit what they do and what's been said, but i think it's important to keep in mind (with one's threat model in mind also) that they're based in Sweden, a 14 eyes country.
What's 14 eyes?
basically an agreement between 14 countries to share signals intelligence amongst one another. effectively, if your data gets captured in Sweden, all the participating states are able to get their hands on it. check out the Wikipedia article for more details on 14 eyes: https://en.wikipedia.org/wiki/Five_Eyes#Fourteen_Eyes
Thank you.
