The "libraries provide Internet access for poor people" argument is incredibly disingenuous. To use an example: My county spends about $22 million per year on its library system. There's about 500,000 people, about 5.9% of whom are under the poverty line. For what we spend on libraries, we could pay for a 4G smartphone and 4G LTE service to literally every single man, woman, and child under the poverty line. And we would have money left over to pay for targeted support services to teach people how to use them.

And unlike libraries, that would be a benefit almost everyone would actually use.
