> Food delivery is great because the full order value can be taken as the top line revenue. If someone orders a £80 meal for four, that's another £80 to add to your top line even though your net revenues were ~£8, if that.
I don't really understand this. Shouldn't the £80 be something akin of gross merchandise volume? What you described seems borderline fraud to me.
I would like to put some time into this, but I wouldn't even know how to go about it. What would the list contain? The names of companies HQed in the UK which produce privacy software?
