I sometimes use the public WiFi of McDs, which often has an invalid certificate. Does not matter so much to me, because I only go to very normal sites from there. I suspect the certificate is from the pre-login contact with Router. As many her know, McDs WiFi uses a Garden Wall, “We warn you this is not private, maybe not safe to logon here,” “Click here to give your permission to acknowledge your risk.”
The McDs website uses Suddenlink Cable, and their website is managed by AT&T, known to have a close connection to “No Such Agency.” The message usually says they are protecting the users, or something similar, this is a bit different message. They usually block Linux Downloads, ISO’s, linux updates. Used to block updates to Firefox (they do not like free software, IMO because- enemy of Profit). McDS public WiFi used to block TAILS download. I wrote to AT&T and pointed out Tails Linux was developed by the US Navy, and gets sponsorship by the US government. Tails Linux may now be downloaded.
I have warned AT&T about the bad certificate, doesn’t get better. At initial contact with Garden Wall, I am encouraged to load the certificate to my browser and tell browser it is all right. I did add it to Edge.
Yes, one can use a VPN to do free software downloads. They do not block the use of Tor Browser.
This is part of the push to only allow limited OS’s on the Internet. OS’s like Windows and Apple. OS’s which I feel are more likely to violate privacy, and be tools of large power groups, like governments.
Smile, your privacy is valued, and your privacy is not really yours, anyway.
