I see your point, but I think rather than it being misleading, you're just interpreting it differently. The way I see it since the recipient is receiving a text - that's using the SMS protocol even if it is through a gateway. The result doesn't change.
As to the second point, yes - I did mean free for the sender. I assumed that people were aware that the recipient can still be charged. I mean by the same logic, you might as well add the recipient's phone bill (if they don't pay per SMS message individually) and even the cost of their phone if you want to be picky. I don't think anything is inherently free. We just have different interpretations.
At the end of the day, I just thought the idea was cool, so I wanted to share it hoping someone might find it useful.
