We know alternatives are possible, because we used to have them. Before private commercial platforms definitively took over, online public-interest projects briefly flourished. Some of the fruits of that moment live on. In 2002, the Harvard Law professor Lawrence Lessig helped create the Creative Commons license, allowing programmers to make their inventions available to anyone online; Wikipedia—which for all the mockery once directed its way has emerged as a widely used and mostly unbiased source of information—still operates under one. Wikipedia is a glimpse of the internet that might have been: a not-for-profit, collaborative space where disparate people follow a common set of norms as to what constitutes evidence and truth, helped along by public-spirited moderators.
