There's no doubt that some fans came to know Wanda then, but the story itself was destructive for her in many ways. One of the most destructive was that she was pulled from comics for 7 years. And it made the character so that writers didn't want to touch her because that meant they'd have to clean up a huge mess. But it also tacked onto her one of the most damaging tropes. The baby crazy trope. When she was the one that wasn't even sure about having kids at first. Vision was the one that was baby crazy. She went to Doctor Strange to make sure that using magic to create children was safe and he reassured her. What AD/HoM did was take all of that and turn her into someone completely irresponsible and selfish.
It got her magic wrong. It took her remembering her kids and working through that loss and completely binned it. Wanda was a leader and co-leader of a couple teams. Now who would even trust her?
It's not really about how popular the story became. Because I feel it was more infamous than famous in regards to her. And that if HoM didn't involve the X-Men and mutants, not many would even know of it. Which is why it gets mentioned more than AD. And no one really remembers when Vision went insane from the possession of the computer ISAAC and tried to take over the world. No one remembers Tony Stark possessed by Kang to kill Avengers and having to be rebooted by bringing in some teenage version from an alt past.
HoM is only known because of what happened to mutants. And isn't the only Wanda story to have sold well nor sold out. More famous of a story that actually has her narrative and which she has autonomy is Vision and the Scarlet Witch.
HoM itself in it's universe was not even about her. It was a story about Wolverine figuring out that the reality was fake. Wanda was wallpaper in it. And her version outside of that reality was in a coma. If you put the cosmic cube in her place, the story ends up the same. She's the lamp in HoM.
