I found in a text that had this question.

why should F, n row 2, be more reactive than iodine, in row 5, while Li, in row 2, is less reactive than Rb, in row 5?

BUT this does not agree with this text

as it is more reactive as you go down in the PTOE.

Notice that your link doesn't say anything about non-metals, where reactivity decreases as you go down. The question is correct.

The reason for the decreasing reactivity down the halogen group shares the same basis as the reactivity trend among the metals (though the trend is reversed). The non-metals or electronegative elements react by gaining electrons, while the metals (electropositive elements) react by losing electrons. The reasons for the trends follow naturally from this.
