You're right that the EU has much stricter baseline consumer protections than Switzerland, but none of the examples you gave are actually part of the GDPR. Insurance pricing rules come from EU equal treatment directives, the 14-day online return window is the EU Consumer Rights Directive, and the USB-C mandate is the Common Charger Directive (which Switzerland actually adopted into law in 2024 anyway).

The GDPR is strictly about data privacy, and it deserves defense on its real merits: it made data collection illegal by default without an explicit legal basis, banned deceptive tracking patterns, and introduced turnover-based fines large enough that tech companies actually had to re-engineer their systems around privacy by design. EU consumer protection directives are great, but it's worth crediting the right ones.
