idk if some of those things are "shadowbanning" per se but more like limiting reach and promotion.
there's the confusion (unaware or intentional) between 'getting actually shadowbanned, as in, your posts actually do not appear to anyone else but you' and 'not getting free promo, free algo boost, free views from the platform, if it either doesn't choose to promote you, or chooses to not promote you' (these two are subtle but different as well). 'not getting the extra boost from a platform' - or just really 'having a piece of content fare for what it is, just by itself'. these kinds of mixups lead to kinda inane takes like 'i'm not getting as many views -> the platform has shadowbanned me', which are particularly weird to actually see, as a post, that is very much up and visible (and not "shadowbanned").
there's almost a vague sense of entitlement to getting views, getting an audience from a platform, in bulk and for free, and for whatever it may be. when a platform really just may choose to not extraneously promote something. or have a more sophisticated way by which some piece of content 'bubbles up', as it gets engagement and moves up in ranks of reach and virality. or it may downrank something, which still isn't a "shadowban". but lo and behold, "shadowbanning" now has its meaning so diluted, you'll just get talking heads throwing it around, and very visibly so - almost as if they're unencumbered by it and just saying a buzzy word.
