Although, I don't agree with your thesis, I think we should err on the side of too much information and points of view than to few. Even if you're completely incorrect (I suspect you are, IMHO spacey flipped when he was outed and this video was a threat to the powers that be to cause PANIC IN DC/PEDOWOOD) notables are not endorsements, and some anon down the line may see this and connect this info to something important.
Hence the reason I didn't endorse it for notables. I only stated my opinion on err on the side of to much vs to little. If I thought it was notable I would have said so.
