I think that you are wrong. My source is https://xmrig.com/benchmark/ Go somewhere to the middle of the page (to get rough middle performance CPU). For example I can see: 984 Intel® Core™ i5-10500T CPU @ 2.30GHz (6 threads CPU). I click it and mean hashrate is 1839. Divide that by 3, you have 613 hashes.

it’s practically free to run the miner

I mostly agree, except no PoW mining is free. It requires to pay electricity, which is obvious.

According to https://explorer.jetskipool.ai/xmr-tracker and https://qpools.qubicdisciple.info/ , that single pool exceeded 51% of the XMR hashrate.

1/3 of the regular CPU resources is around 1000 hashes per second according to my calculation. We would need 1 million such users to produce 1 gigahash per second. The 51% attack currently needed around 2.8 gigahash per second.

All the Proton software which you can install is open source. It makes sense to have some internal software source code not disclosed.

The data are not logged, not used to improve the AI, as stated. https://proton.me/support/lumo

“Your chats with Lumo are stored with zero-access encryption, so Proton can’t see your chat history. Only you can securely access your conversations by logging in to your Proton Account.”

“We’re pleased to announce that Proton VPN has passed a third consecutive annual third-party audit of our infrastructure that confirms our strict no-logs policy. When we say we are a no-logs VPN, it is not just a claim: it has been double-checked by independent experts.” https://protonvpn.com/blog/no-logs-audit/

Many people wants to use AI and this is a private alternative and so feels like appropriate part of the Proton’s ecosystem.

It speaks foreign language well and is not much factually accurate. Design is good.

Since F-droid lacks official Proton apps, I ended up using F-droid to install Obtainium app, which allows installing apps from Proton apk or official Proton Github and keeping it up-to-date from same source. I have used these links in Obtainium:

https://proton.me/download/DriveAndroid/ProtonDrive-Android.apk

https://github.com/ProtonMail/android-mail

https://github.com/ProtonVPN/android-app

Not found Pass, so I have Pass from a F-droid directly.
