Those unfair tactics, assuming I accept they existed⁰, were not twitter's by my understanding, but reactions to the whims (or perceived possible whims) of advertisers, or the bulk of users that advertisers were there to claim the eyeballs of.
I'll caveat this by saying I've never had a twitter account or any desire for one¹ meaning my views are those of an outsider and occasionally a passive reader – but from what I can see twitter acted from a position of cowardice² rather than any political machinations.

[0] One man's fair slapping of an arsehole, is another man's unfair restriction of speech.
[1] At first it was a daft novelty, then a novelty that had perhaps outstayed its welcome, then just a place far too full of people who thought twitter was a good idea, then the famous got hold of it and it became a tribal shit-show & soon after a political shit-show – all before Musk jumped in with both feet and a lot of other people's money.
[2] Hence not kicking Trump (and a few others close to him or relevant rhetoric) despite flagrant breaches of their stated policies, until such time as he was a lesser threat due to not getting a second term, and before that kicking people not because of any internal moral code but because of what advertisers might think.
