Re: 'Why does it do that? Because it is worth a lot of money to Google'
"1% of turnover could be seen as "Cost of sales" and worth the risk."
Note that you said "1% or turnover" twice. You are correct in that respect. But note that 1% turnover is usually way way higher then 1% of profits. Even Google will be hurt by a fine of 4% of global turnover, if the fine is that large. This is why the GDPR specifies turnover, not profit as the measure of the fine at a global scale. So the likes of Google, Amazon etc can't weasel out of a serious fine by claiming they make no profits inside the relevant jurisdiction.
