is it true that hargreaves lansdown get huge kick backs from the funds they promote?

An article here:

I don't know what level of commissions Hargreaves get, but I suspect they would query the words 'huge' and 'kickbacks'.  They offer a service, for which they need to be paid, which either has to be by a fee from the buyer or commission from the seller, or a mixture of both.

If you know what fund you want then there are many 'supermarket' sites that will allow you to shop around.

This is truly huge business for them (35% of their total revenue last year).

Low cost fund supermarkets will have to declare how much they receive from the fund groups from 2013 onwards

going to be mildly amusing when the know it all diy investor crowd realise that investing this way is quite expensive

like an idiot i invested 20k in funds with h/l because they waived the initial charge. so in future if i wish to invest in a fund how should i go about it?
