County libraries near me are open until 6pm MWF and 8pm TR, along with all day Saturday. Plenty of opportunities to head over after work ... assuming you have a job (and if not, you can head over at 10am when they open to look for one.)
But this is just incrementalism at play. To go with the subsidised net service, these poor folks will need a computer ... so they get the $145 discounted unit provided by Comcast and their ilk. Then the end user will cruft it up by clicking on every "get rich quick" spam he received, so there's going to be a need for subsidised IT support services to de-cruft theise machines (because they're clasified as "essential services," they can't be denied.) And in the interim, the machines will end up participating in botnets, motivating Comcast (etc.) to petition for funds from Uncle Sugar to build out additional capability to support the increased network load. After all, it's only fair that the government pay for the additional traffic burden imposed by these Lifeline program machines.
Never seen a government program that didn't have a voracious appetite for cash. This one is no different.
