For me personally: I really enjoy tiktok. My feed is curated enough over time that I only see stuff I’m genuinely interested in, comedy, science, tech, fitness and ofcourse skimpy dancing ladies. I do not suffer from the so called propaganda on it.
I agree that tiktok melts brains of teenagers, but so does Instagram reels, facebook and YouTube shorts. So that isn’t a tiktok issue in itself anymore.
I use windows. I haven’t paid for a windows key since windows 7 iirc. Windows has been free for years. (I know you pay with your data etc. Good luck convincing average Joe who uses all social media services that this even matters)
