The man of culture part was.
Generally I think the dislike of Tiktok has to do with purity culture more than anything else. I typically find people who hate on Tiktok to be misinformed, willfully ignorant, massively hypocritical, or a combination thereof
See, this is the purity culture, and it's always so selectively applied.
Things can have both good and bad aspects. Lots of good things can be bad when used too much.
Lemmy is much the same way. You say it was specifically designed to be an addiction engine, but all that involves is showing you things you like. Lemmy is the same, just that the algorithm is so simple that it can't show you any discovery or new things.
You can find similar arguments about almost every part of the internet.
Are there problems with Tiktok? Of course. There are also amazing parts of Tiktok. Just like Lemmy. Just like Mastodon. Just like pixelfed.
