There's no such thing as a free lunch is as true today as when it was first written in the 1930s, as well as it's likely origin in the once common practice of saloons in America offering a "free" lunch to any patron who purchased at least one drink.
Today, you can take that adage and attach it to a number of scenarios in technology. There's no such thing as free email. There's no such thing as free software. And the one we're talking about now - There's no such thing as free wifi.
We'll skip the obvious part about how you paid for the hotel room with "free" or complimentary wifi, or the Starbucks you purchased to sit and enjoy as you use their "free" wifi, or the "free" wifi now available when you walk through any number of retail stores like Target. Instead we're going to talk about something many people consider much more insidious - Adware injected into webpages on "free" wifi networks.
The next question, at least for anyone techy inclined, was had the hotel's wifi been hacked or was their something more malicious at work? Could the hotel's ISP be involved? Had the hotel itself brought in this technology to influence guests? Justin was also concerned about who could be notified, who would care about this invasion?
Computer companies spend a great deal of time removing Adware from computers and as a result users spend a great deal of money paying to have Adware, Malware, Viruses and Ransomware removed from their computers. But this is the cost of being online; the Internet is crawling with things we don't want on our computer and we'd like to believe that when using "free" wifi the company providing it has our best interests at heart and has put security in place to keep our systems safe. Sadly that's not always the case.
From RG Nets site, "...the rXg is the perfect platform for clear communication, authoritative control and complete cognizance over your RGN end-user population." If that doesn't make you weary of ever using "free" wifi again I don't know what will. RG Nets site goes on to say, "...profitable IP RGNs extract revenue from the end-user community through a combination of direct and indirect mechanisms."
A demo video is available on RG Nets site. A portion of the video transcript, "As you can see the pervasive nature of the advertising banner on all webpages guarantees banner advertising impressions. The RGNets rXg HTML payload rewriting feature is a tremendously powerful tool, with a broad spectrum of applications for Internet marketing programs." YIKES!
For anyone traveling through Atlanta's International Airport they are listed as an RG Net rXg success story, so be wary of what you see on our screen with that "free" wifi. A local Nevada success story is the Peppermill Hotel & Casino where the rXg is "...used to advertise resort amenities, restaurants, gaming specials and events." At the Peppermill the rXg is also used to charge for different levels of access including, casino patron, convention attendee or exhibitor, and overnight guess access.
While the Marriott came out shortly after Justin posted his blog and said, "...this functionality has now been disabled." this article does not appear to have harmed RG Nets, although it appears to purchase an rXg you must now contact them directly through a contact page on their website.
