Several of the alternative video distribution systems can be self-hosted since they are based around P2P video distribution (PeerTube uses webtorrent, odysee uses LBRY) so it will be possible to get around censorship as long as the network providers keep from colluding with the censors to keep out content which does not fit the desired narrative. Even if they do there are ways to get around this censorship but this makes it harder for normal users to access the content.
That bit about serious information being for people who cross-check information etc. would work if they were allowed to access all sources, something which is made difficult by certain viewpoints being blocked by several of the largest distribution platforms.
What you say about "no place on the 'net being for serious information on its own" is not necessarily true, as long as the above conditions are met - i.e. no network-level censorship - it is possible to present an overview of the current level of understanding on a subject. This used to be the case in scientific journals, nearly all of which are available online. The SARS2-pandemic made short shrift with this reliability when many of the journals started to align with the desired narrative, sometimes by simply refusing to publish studies which went against the narrative [X], sometimes by actively publishing false studies [1,2].
[X| here there would be links to papers on the seemingly proven efficacy of Ivermectin, the potentially useful nature of Hydroxychloroquine, the "statistical certainty" of the virus having escaped from the Wuhan institute of virology, etc. Alas, there are no such links since the journals refused the articles even though they were written by people with a proven scientific background and came with a bevy of evidence. Had the articles been published they could have been discussed in the open and their contents thereby proven or disproven without fear of retribution or cancellation since the works appeared in well-known and -respected journals. Now this is impossible, those who try to bring up articles published in less well-known journals or aggregators like arXiv often find themselves accused of quackery - which was the purpose of forcing those articles to be published there. For the respected journals this is a case of 'mission complete but reputation tarnished'.
