In general, I completely agree (though I have never seen it happen before). This is not a link, however, but a bitcoin address encoded as a QR code.
I - as do many others - have a Bitcoin wallet application with some change on my phone. Having the QR code here makes it easier to contribute something.

Slightly OT: Why would you ever put a QR code on a web page instead of a link?
If I'm on my computer, I'm not going to pull out my phone to scan it. If I'm on my phone, how would I even scan it?

Its for times when you want to open a link on your phone when you are reading it on the computer. Like the Chrome to phone chrome extension.
