1/2 We have replied to the email sent to O2. Many thanks for your swift response to our change.org campaign regarding your London Underground advertising campaign for the O2 Refresh product. Having read your email, we can only conclude that although you have certainly given us a lengthy response, the issue at the heart of the campaign has not been addressed. We are primarily concerned with the wording and tone of the advertisement which seems to take an antithetic angle on sustainability, encouraging customers to change their mobile phones as often as they do tubes. As you are no doubt aware, the mobile phone industry (along with other tech industries) has received a certain amount of negative attention in recent years because of the culture of planned obsolescence. This in itself is an inappropriate approach to take for manufacturers wishing to promote an image of good corporate citizenship.
