You seem to have misunderstood my reply. I don't know when you last bought software on the Net, but it's been required that companies charge VAT for EU citizens for many years now.
You say you would rather buy direct from a UK company, but if you do, you will pay VAT, just as you are expected to on the Net, so I don't see why you have a problem with it.
The reason I mentioned poor people is that if you had to pay VAT on purchases made in shops, but not on those made over the net, then people without internet access would be unfairly disadvantaged. As those without Internet access tend to be the elderly and the poor, this would mean that (generally speaking) the people least able to afford it would be subsidising the better off.
So the question remains, "why do you think that a purchase should be tax-free, solely because it's made over the Net?"
