I always wonder why Google don't start charging for Gmail accounts for non-OECD countries or other countries where the ad rate means they make a loss.

Because everyone there will move to first available free email alternative. Everyone else can easily pursue the same business model. Instead of gathering data for other services, other providers will build profiles and just target the users with paid email campaigns.

Lower ad price area means almost same as lower income, so they can't charge.
