Leaving aside the "OH NOES! TAXES!" BS, the statement you quote never suggests that supplying Internet access is "charitable" or "unprofitable". It says "the majority of the area does not present enough profitability to attract the private-sector investment", not "the majority of the area does not present profit to attract the private-sector investment".
The private sector generally doesn't invest in projects to make small amounts of profit, especially if they're expensive. There are many, many, examples of projects that would more than pay for themselves that you'll never see the private sector take an interest in, because the promise of a 10% return here for a medium risk is unattractive compared to the promise of 100% there, for little or no risk.
As for taxes, I personally like paying taxes. As a wise man once said, in return I get civilization.
