Except Google Analytics cannot be a "legitimate interest".

A legitimate interest is one that prevents the service from operating. E.g. if you're a pizza delivery service, you need to use the customer's address, since it's implicit in what the service does and the customer expects you to use their address for the purpose of home delivery.

If you block Google Analytics however, in what way will the service be impacted from the perspective of the user experience? There is no impact, even if this costs the business optimization opportunities or money. You can argue that the inability to use Google Analytics can have a long term impact on user experience, but that's not how legitimate interests work.

In general, "making more money" or "becoming more popular" are invalid reasons for stating a legitimate interest.
