McDormand has had a lot of low-key fans since the 1990s who have enjoyed her work and don't hang around the DL and other circles who consume copious amounts of entertainment media. I remember working as a temp in the mid 1990s and a coworker thought that McDormand was America's answer to Emma Thompson (who was at the peak of her popularity having just won her second Oscar--for screenwriting this time). These were my coworkers's words, not mine, and really liked her.
After winning her first Oscar, McDormand then worked under the radar with a solid, subtle run. She worked with Curtis Hanson right after L.A. Confidential and Cameron Crowe on his most appreciated film (continuing to stretch her range as an actor). If you seen Laurel Canyon, you've had the opportunity to enjoy her work as a rockstar who couldn't give two fucks. That same year, she showed she didn't mind playing second banana when it meant working with legends like Nancy Meyers and Diane Keaton. She got her fourth Oscar nomination two years later and continued to work with hip female directors following up Meyer, Lisa Cholodenko, and Niko Caro, with Nicole Holofcener. This wasn't by coincidence, but design. Whilst men still held most of the cards, she worked with what was available in the directions she wanted to go as an actor.
She continued to work with respected directors like Paolo Sorrentino, Gus Van Sant, and became part of Wes Anderson's stable of stars. The respect, IMO, began to increase more for McDormand in 2014 with Olive Kitteridge. Its power was lost on me, but the limited series won 8 Emmys, including one for McDormand, who also won SAG. She even became a meme that award season fanning herself like she was having hot flashes whilst losing patience for the pomp and circumstance of awards ceremonies. Two years later, Three Billboards came out and, at one point, was the frontrunner for Best Picture. At 60, she was picking up for second (lead) Oscar. She followed that up with two more Oscars last year.
OP seems insistent that what's happening is this "fake" revisionism: that, suddenly, McDormand is considered this revered actress for decades, when actually no one cared much about her as late as 2016 (according to OP). I think the problem here with that thinking is following the promoted hype that other people shill and accepting it like it's what everyone else thinks. And, as R37 pointed out, this just wasn't McDormand's bag. She deliberately avoided it whilst consistently holding and developing the respect she built from her industry and audiences. One could argue that the industry really started catching up with how some audiences felt about her all this time back in 2014. I'm not insisting this is the truth. But, it is another way of thinking about things, I haven't read the Vogue article and really have no interest. I'm not sure why it gets under OP's skin, but it's kind of funny.
