How Much Do Customers Care?
I think Umair means to highlight the importance of corporate purpose in the mind of the consumer though he tweets a little ambiguously. If that's a correct interpretation, then he's positing a prevalent thesis. One that's certainly useful to think about, albeit one that equally can lead us astray if we focus on purpose at the expense of the basics.
Look around at what people do and look at your own behaviour. A "moral" element might be the deciding factor in a choice between equals. While I'd like it to be different, I'd currently contend that most of the people, most of the time don't care - for a variety of reasons that include but are not limited to personal finances, convenience and ignorance.
That said, never, never forget that some of the people some of the time still constitutes a very big market.
