For those who can read only what they think is written and not what is written, I repeat "if ubercart need this to create awareness, it means it's lame. If it's not lame, then awareness will happen."

Now, yes, we can hack the module or override the theme function, fine.
But it should also be implemented in the function, in the settings where we can choose which one of the 3 keyphrases we want to display, to be fair there should be an option to not display the footer.

Anyway, as for the rest, I was simply voicing an opinion about the ethical speech, nothing about ubercart itself or even this search engine strategy.
