Your question is meaningless and context-free.

The only difference with "unsecured WiFi" is its lack of key and encryption.

You've said nothing about who provided that WiFi service, where it was, or anything. Plenty of reputable and well-managed WiFi networks are unsecured these days. Even my ISP runs them; they're perfectly safe. I don't use a VPN.

We're not your tech support department, and it's impossible for us to troubleshoot your bugs with so little information. Your local machine got messed up somehow. It sounds like PEBKAC. What leads you to believe that the WiFi network was to blame? No, I don't care.

Take your machine to an Apple store or something. Contact the administrator of the WiFi network. Go to Geek Squad. Factory reset and reinstall your computer. Who knows how you've shot yourself in the foot?

What a weird reply to a call for advice. 'your machine got messed up somehow'. They now that, provide some recovery tips instead of downplaying.

"You're wrong, but I don't feel like teaching. Just feeling smug about my supposed superiority."

I have negative feelings towards this sort of long winded holier than thou garbage.

And it's a documented self inflicted "why does nobody want to contribute to $project?" By burned out devs.

Perhaps I could be less condescending, but is it not teaching, and constructive feedback, to warn this poster that it's impossible to diagnose without much more context, rather than engaging in wild speculation like other commenters? It would seem that they're the harmful ones. And I did suggest several avenues for superior support, rather than trying to tackle it all alone.
