Competitive re-branding

We have this tendency of over-praising our products and services. And the limited extent to which you can do that is absent in books by marketers (originally of West and their copy-cats in east). I's listening to a lecture on Ethics of Trade in Islam, in which Abdal-Hakim Murad was telling that Allah on the day of judgement would look upon a man who took oaths while buying and selling. That's a little bit complex to understand. Applied to bragging we do on our trade, it fits the paradigm. Billions are spent by Coca-Cola on "re-branding", they talk about "brand loyalty" and brand this and brand that . . .  Human and natural resources are slaughtered blindly in this mania of over-advertising. How despicable and ugly the practices of moderns who are cut off from revelation . . .
