Why is "Middle force opposition to the Marcos dictatorship" trending?

Wikipedia Overview

In the Philippines during the dictatorship of Ferdinand Marcos, groups and individuals which opposed the regime without subscribing to leftist ideology were usually labeled with the terms "middle force," "third force," the "mainstream opposition," the "moderates" or "centrists," or more rarely, as the "conservative opposition." Mostly consisting of middle class and upper class groups which had been apolitical when Marcos first declared martial law, the most prominent examples of oppositionists in this category include religious groups, business sector groups, professional groups, social democrats, academics, journalists, and artists. Politicians from the traditional opposition are also sometimes counted in this category, although the terms are traditionally associated with ground level opposition, rather than political opposition per se.
