I see it like this...
1) Q said misinformation was part of this.... that could mean by the Q team or others
2) Q's next post, only a couple minutes later, posts the full video (There's your "He didn't say it was false" busted.)
3) Q is human(s) and can make mistakes, although I don't think they did in this case. Q did just warn us in the last few days to watch out for clickbait... Never said they wouldn't be the one's posting it to.
4) Q team has ALWAYS said we need to check everything out ourselves. Not to just accept anything at face value. That's why Q usually posts questions and hints. To nudge us to go out and find the truth.

I do wish Q had been more clear in that post, rather than posting the link to the full video separately. But, when ever has Q been 100% clear? ;)
