That is not true that most of the world doesn't have internet. Multiple sources say it is about 64% by now. You should be careful about thinking the world is worse off than it is. Thinking former developing countries is worse off than rich countries is most of the time a outdated world view.
It is equally unhelpful conflating number of internet users with coverage and internet accessibility.
It is of no good to you that you have internet connection but the website or whatever doesn't load because you are only on a slow cell phone connection somewhere in the middle of Africa or India, where cheap "feature phones" are the only way to access internet (and thus government services, for ex.)
Or if you have connectivity in the capital and one or two major cities - and the remaining 90% of the country is "dark" because of missing infrastructure, both electrical and communications (many African countries).
Txti was created NINE YEARS AGO with a simple and benevolent mission: to play a part in a more globally accessible internet. Since then, the whole world has changed. Now, there is less need for web pages that work on flip phones[...]
- from the linked page, emphasis mine; presumably the about page the "most of the world does not have internet" line comes from was also created nine years ago.
