Should there be a non-refundable tax credit for spending on online subscriptions to periodicals?
Delivery of paper copies of newspapers and magazines can consume non-renewable fuels, create pollution, etc.
However, it's difficult to see any such concrete downside to increases in circulation of periodicals by means of internet distribution. People watch streaming video, and a few minutes of that can consume more bandwidth than is consumed in transmitting an entire newspaper or magazine.
At various times, it has been thought that if people are to be trusted with the power to vote, then they should at least be able to read and write. However, somebody who has the ability to read might choose to instead merely watch television, or listen to the radio. Perhaps reducing the cost of reading might have valuable side-effects, not only for the people who do the reading, but also for writers and for publications that nowadays have experienced reductions in their advertising revenues.
