If you've ever achieved a few million views in Facebook you would appreciate that it is laughable that it can meaningfully move any needle. I figure most people would stand by that assertion.
if you had read the article before reacting to it, you would have known that the estimated number was 140 million, not 'a few', and that the russian troll operation got viewed (and, troublingly, promoted by Meta owing to its engagement metrics) by almost half of Americans.
