I feel pretentious to continually quote 1984, but those slogans seem eerily close to the way that the Party instilled propaganda through slogans.

Every form of language is super effective. But I believe if 100 people around you say the same idea, and only 5 oppose it, you will believe the 100 people. Since digital media is so easy to upscale to thousands, and even millions of users, I believe digital language has the biggest capability of making a change (good or bad (often bad imo)).
