TikTok is where I find fun on the current internet. It's hilarious (Taylor Swift private jet memes), weird (grimace shake), surprising, emotionally moving (hopecore), educational (how to adjust a door closer), and always exposing me to things I've never seen (starting process for a diesel locomotive). It contains ads, but they're pretty easy to identify and very easy to skip.
The reality is that TT, like all social media, puts people on a hamster wheel of 'content creation'. Post about this, not that. Post using code words if [geopolitical event] is advertiser-unfriendly. Post something every single day so that the algorithm deigns to distribute your post to randomly selected buckets of users across the globe.
I skip the ads on Tiktok too, but at this point, even regular videos desperate for engagement are effectively ads. Taylor Swift memes, or memes related to [popular IP] are ads, just delivered by unpaid civilians.
