On one side of the pond, we have the EU's Digital Markets Act to protect consumers. It has teeth and it's already being used to ensure consumers have choice.
Not so sure that EU bureaucrats will understand and fix that problem. With NIS2, they let the IT-security-crapware lobby dictate draconian and mostly stupid security laws. Could be that the security-paranoid part of the bureaucracy overrides the consumer protection part in that case.
