When they objective is to shake down a mark, you dont want to bleed them dry on the first go. You take a little here, and a little there. That way you can shake them down for years and years.

The Euros dont have any meaningful tech companies of their own. So they can shake ours down without much risk of retaliation.

But yeah. Like a mafia shakedown, these fines are just a cost of doing business. If the EU were actually trying to promote good policy, they'd fine the shit out of these companies, rather than take their lollipop money.
