You are the OP, you literally removed someone's tweet from it's original context (or reposted without fact checking) and presented it here with an entirely different, false context. The fact that it's being misinterpreted is 100% on you for presenting it inaccurately, not the guy who's words you misrepresented.
I actually upvoted this before deciding to fact check which took me no more than ten seconds.
I think quote posts are undesirable for the reasons you mentioned but I have to accept that it will be huge for adoption, and the flip side (promoting others work in a positive light) is also going to be really great.
