"The strength of activists, social change, and opposition movements seems to be decreasing around the world. The trend is reinforced by the seemingly old tactic of discrediting, deception, building mistrust among members, and disinformation spread by various political and state actors, who over the millennia perfected their methods."

Could the decrease in "strength" (i.e. interest and involvement by its participants) be possibly due to how unpopular the demands of the activists are to the general public? It seems the author has a very myopic view of the situation. People are seeing what "defund the police" leads to, and what their kids are being taught in schools -- they see it, and they're judging it, and their response is increasingly "NO". The democrats in the US see their polling numbers plummet, and are recognizing that pursuing the agenda demanded by the activists will take them out of power altogether.

The examples cited are COINTELPRO and the Soviet Stazi? Those were quite a long time ago, and not at all part of any suppression of today's activists. The article fails to mention that for the most part, "big tech" has supported opposition movements, and show clear bias against conservatives.
