Has The New Yorker changed its "who"/"whom" policy? Recently, I noticed--for the first time in fifteen years of more or less consistent readership---two occasions I considered non-standard, both from 2018:
A couple weeks after that, a woman in California called the police on three black women whom she thought were behaving suspiciously.
("Smelling the Coffee" by Jelani Cobb, June 4 and 11, 2018)
They spoke to P.J. and to the men memorialized in Kavanaugh's 1982 calendar as Timmy and Squi, along with Mark Judge, whom Ford says watched Kavanaugh pin her down and try to undress her.
("Bystanders to History" by Amy Davidson Sorkin, October 15, 2018).
Compare these to the magazine's long history of making the opposite choice in this context:
Warren targeted the one person in the White House who she believed could stop the legislation: the First Lady.
("The Virtual Candidate" by Ryan Lizza -- and at least 20 others containing the phrase "who he believed," and 298 containing "who he thought," for a quick and dirty initial survey. [Perhaps notably, the magazine seems to have started insisting on commas around such clauses not long before its apparent switch to "who."])
What explains this change?
