Every time they use a public wifi hotspot. Any time you use a network you don't control and where you have no reason to trust the admin, you may as well be using a proxy.

The requirement to trust the admin isn't about the admin MITMing you, but rather trusting their competency in preventing other users MITMing you. Of course the admin could be bad as well.

Fair point. But if they have gone to this extent, they could just as easily inject some code into the HTML no?

They're talking about what happens when you load an infected jquery.min.js from cache when you get back to your home wifi network.

Any time you browse via public wifi you might be being fucked with. How often are you actually? My wager, depending on setting, very rarely.

In your local starbucks? Probably very rarely. In the VIP business lounge of an major international airport? I wouldn't be so sure in this day and age...

In the cafe on the corner of your block in syria, iran and similar places though, the odds are a lot better.

Yay for never using public wifi hotspots, now if I could only impress that upon the millions of Americans who do so everyday...

I set up a VPN server at home on an old laptop, it works well for me in these scenarios (also for location-blocked services like Netflix while travelling out of country).
