> 6% is the cost of sales tax in some places. That is not considered any kind of correction to bad behavior - it's literally the cost of buying goods in a variety of places.

6% of annual, global sales, as an extra cost from one jurisdiction, which can impose this multiple times if there are multiple breaches, and where they're not the only jurisdiction with such rules, and the DSA isn't the only ruleset where fines are based on global revenue even in the EU (famously, GDPR).

Or, to put it another way: 16 such fines in one year and you've lost 100% of your revenue. You don't get to make up for this by raising prices, because that just means "100% of your revenue" is now a bigger number.
