Things that make you go WTF

What do you think, do they make a profit off text messages?

Why Are Text Messages Marked Up 4876%?
Verizon and other cellphone companies mark up the cost of text messages by at least 4876% when compared to their rates for data transfer services.
Verizon's max text message size is 160 characters. At 7 bits per character, that's 1120 bits or 140 bytes. Without a text messaging plan, those 140 bytes run you $.10 (ten cents), according to Verizon's website.
Compare that to the rate for data transfer (like when you would use your cellphone as modem). That rate is $.015 every 1024 bytes.
That's $0.0000146484375 per data byte versus $0.000714285714 per text message bytes. In other words, a markup of 4876%. Other cellphone companies charge comparable rates.
Bytes are bytes. What makes a text-message byte so much more valuable than a straightup data byte?
