I think the same is true for the Trump CPAC speech article. The blog post compares the initial headlines about him “claiming leadership” to the ones about him attacking other Republicans. But just from eyeballing the chart, first the headline changes from “Plans to Claim” to “Claims”, presumably around when he started giving the speech, and then shortly afterward it’s changed to mention him attacking Republicans, probably at the point in the speech where he did that. There does seem to be an A/B test between the last two headlines, “Trump Pledges G.O.P. Unity, Then Attacks Republicans Who Backed Impeachment” vs. “Trump’s Republican Hit List at CPAC Is a Warning Shot to His Party”. But that’s not the comparison the blog post makes. And among those two, while the winning headline (the second one) is clickbaitier, both focus on the same part of the speech, and neither is inaccurate.
