Except the email in question is not a newsletter. Companies often use separate mail list services for important product announcements and similar things as well. Obviously there should be a process in place that removes you from these external services too when you delete your account, but I assume this is what broke down in this case

You’re thinking of Edge, not Internet explorer

For those not willing to give up on convenience, on Android, there’s Lockdown mode, which will temporarily disable access via biometrics and force the use of your PIN/password to get into your device. Not sure about other brands, but on Pixel, you can enable it by long-pressing the power button and tapping on “Lockdown”.

Not if the site is actually GDPR compliant they are not. You are only allowed to set tracking cookies after consent has been obtained, which cannot be assumed before the visitor has made a choice.

What exactly do you mean by “trust”, here? Yes, it’s not fully FOSS, and I do understand why you wouldn’t like or use it because of that, but you can still verify the code, compile it yourself and build and run it with your own modifications, so how would being fully FOSS make you trust it more?

Makes sense, thanks for clarifying!

How can I find your public key without going through a channel that could also have been manipulated by the admins, though? That seems problematic to me
