Working on a low margin business is a choice! You can always ditch it and try to find something with higher margins (= higher value created for users).
Google doesn't need to provide a service in that country, but it's understandable that a 20× increase is going to hit harder than in a wealthy country.
I am only pointing out that entrepreneurs need to rethink their business models if they are hit by this price increase, as this is a very strong indication they are not working on a healthy, high-margin business.
This is what happened to OP, and they were able to switch to haf a dozen competitors at a fraction of the price with almost equivalent service offerings for their use-case. The notion they have a fundamentally unworkable business model doesn't apply here.
