Meta have been fined over a billion Euro last year alone due to GDPR. Maybe one can disagree about that being large but it's still a relatively new law showing a trend.
Do you still think it's a negligible cost? These costs are also going up: in January 2023 Ireland issued two more fines for $0.4 billion.

Ireland's data privacy serves as Meta's main regulator in the European Union because the company's European headquarters are in Dublin. Making it out as if Ireland's GDPR fines are "just one country" is disingenuous.
