As a reader, there's a real difference between deciding to upvote the original title (an observer's description of an inherently deceptive project) versus casting a vote on what it's been changed to (a brand name used to promote that project). I would absolutely upvote an article critical of The Spinner - while at the same time, I'd downvote a promotional submission.
OP did not intend to advertise The Spinner, they intended to expose it as a deceptive project without linking to third-party press coverage. The submission title absolutely matters.
If this changes your mind, please go with the original again.
The HN guidelines do ask submitters to use the site's title "unless it is misleading or linkbait" (https://news.ycombinator.com/newsguidelines.html). That's why we changed it.
Point about importance vs. endorsement is well taken; I would rather not give any publicity to this project without couching it in explicit criticism, but that's a personal choice.
