How are you expected to memorize button combos and directions for fighting games?
They answered you with practice which is true, but it consequently furthers your muscle memory on that action.
Have you done something physical repeatedly, where it used to be difficult at first, but through repetition you can now do without even thinking?
It does not have to be something physically exerting, it just involves coordination of muscles in a way that's efficient and flows naturally, from riding a bike, to doing moves in basketball, to doing simple tasks or motions like flipping/spinning a pen in your hand.
I don't get being demonized for running an adblocker. I expect it from corporations, but when normal people do it I have to bite my lip to keep from asking what's wrong with them. Do they want their time stolen from them?
I can't speak for all cases, but some do because of morality issues according to their standards, like sometimes with piracy.
Imagine you're watching a small streamer and you put ad-blocker on,
some would take this as selfish because you're consuming their product for free, but don't bother to at least let them earn ad-revenue through your views, so it ultimately hurts this content creator & their ability to continue making stuff (because this supposedly takes time, effort, and even resources, depending on what it is).
The line of thinking may extend to not-so-small streamers or big productions, because even though your lack of contributions may be negligent, if everyone starts doing it, then the result will be the same as with the small streamer. It also introduces the problem that if you were to "morally allow this", you'd have to set an arbitrary boundary (i.e: how big do they have to be for me to be justified to deny them of my views/ad-revenue they get from me?), and what would be the justification for you to be able to do this and not the others (so if it's just you, there's no problem), but if you can then so can others, and when that happens, the creator (even if big) will incur in losses (specially when the product mainly relies on ad-revenue and not sales/purchases, like with a YouTube video).
That's one reason I can think of, this alongside piracy however is a grey area, there's no intuitively """correct""" answer.
