What is he talking about, public WiFi can easily poison and monitor your DNS requests (most people don't know or use encrypted DNS), and there's still tons of non-https traffic leaks all over the place that are plain text. Even if encrypted, there's still deep packet inspection. VPNs can mitigate DPI techniques and shift the trust from an easily snoopable public WiFi to the VPN's more trustworthy exit servers.
This guy really needs to elaborate on what he's trying to say when the cyber security field very much disagrees with this stance. I'm not a huge fan of Proton, but they aren't doing anything wrong here. You should use it for public Wi-Fi.
I'm not even an expert in this stuff, but with a tool I found online I demonstrated that it was easy to snoop people's passwords on my school's wifi networks back in the day. It took minutes.
That must’ve been quite a while ago
I mean, yes, I'm in my 40s, but it's just as effective today.
I’m sorry, but I don’t believe it is. Nearly all traffic is TLS. When this is attacked, you’d get TLS error. Am I missing something?
There exist plenty of services on school campuses that send passwords in plaintext. There are services outside of school campuses that do, too. Hell, I've been able to bypass 2FA checks by just navigating around them, I don't know what else to tell you, not everything out there uses the best security practices, so don't assume that they do.
I guarantee you it's not.
