It is a dangerous belief that anything you publish can be 100% reliably unpublished, even if you use a centralized platform that grants you the button to do so

It is a dangerous belief that anything you publish can be 100% reliably unpublished, even if you use a centralized platform that grants you the button to do so. Information does not work that way. However, a centralized near-monopoly grants itself certain power over the spread of information: if everyone uses it and it bans your video, the video may essentially be unknown—despite your intent. That is losing control, both for you personally and for us as a society: we lose control of our videos by using one big centralized platform, which lets it hide them from us. An interpretation of PeerTube’s slogan could be that switching to it you take control of your videos by making them less liable to become hidden due to e.g. censorship—but also in that publishing something useful on it you by extension also bring viewers into the ecosystem and thus help society as a whole take that control back by reducing its dependency on a centralized source.
