They are in transition, so for the moment I believe them to have technical problems, because it also matches my experience. Yesterday I encountered problems with several videos, which are working today. And not all of them were political.
Going by the comments, people on TikTok seem very fast in seeing conspiracies, when many problems can be simply explained with normal problems or human failings. And it's good to be critical and aware of dangers, but I fear if they are so easy to call out problems, it will wear of fast, and people will start to ignore real problems again, like they used to be.
