It seems you've misunderstood my comment, as I mostly agree with your points. I'm just saying that the idea that startups need to get a lawyer involved to cancel your subscription is unnecessary. This seems like a pretty clear case of a fuck up on Carta's side, and usually when fuck ups are this obvious if you just point them out the company goes "Oh shit, sorry, we fucked up", which is essentially what happened here.
Did it? The response from Carta, as quoted in the article, was basically 'You still need the meeting, but the scheduling is was a one-off and we should be good now, otherwise you can always chat with us online'. I definitely don't see any 'Oh shit, sorry, we fucked up', it's definitely still 'That was just a glitch, all is well, continue to trust us'.
