Might have been an overeager packaging designer that printed that and then filed a ticket for someone to set up the redirect and that ticket is still in the person's queue.

Or it's something about your own connection. Maybe an ad blocker? For me, the redirect works:

    $ curl -IL logitech.com/mx 2>/dev/null | grep http
    Location: https://logitech.com:443/mx
    location: https://www.logitech.com:443/mx
    location: https://www.logitech.com/en-ca/mx.html

(I have the Mechanical Mini keyboard and the 3S Anywhere mouse; I like the MX product line.)
