Am I the only one annoyed by "A donor has agreed to match your donation up to £xK"?
Either they have decided to donate £xK or not. If they have, this is deceptive and in fact small donors are being asked to match the big donor, not vice versa. If they haven't and will only give e.g. £0.5xK if the campaign fails, then ... WTF is going through their minds? Conditionalising their charitable giving on, let's be honest, popularity is extending market thinking too far.
