Not really, Hermione was operating on a war time level of thinking, even if it's only subconsciously. She did nothing wrong by giving Marietta a clear mark that she betrayed Hermione and everyone else's trust. By the point the DA is formed Umbridge had already made it very,
very clear to Hermione that she was a serious threat to herself and her best friend by torturing Harry with those quills and preventing students from learning how to protect themselves when there were serious threats to them outside Hogwarts, and inside.
So Hermione took measures to prevent and punish people sharing critical information. Even
if Marietta was tortured into giving up the information, she still was a
betrayer. But she wasn't tortured and she broke the rules despite being told there'd be consequences if it occurred, so that's her own damn fault. The clear marking of that in the form of acne is still incredibly important to keeping people safe, because it's a clear sign that shit has gone wrong to everyone else in the DA and that they aren't safe because someone said something they shouldn't have. The fact that it occurs in a way that is incredibly damaging to one's social standing and physical appearance is just icing on the cake to Hermione. Yeah Marietta is fucked over for life, but this isn't a situation where you can be careless because it's a matter of life and death for dozens of people. Rita had also personally lead two smear campaigns, one of them so bad that it lead to serious bodily harm, against both Harry and Hermione by that point. And that's not even going into the issue with Hagrid or Remus being hurt by Rita as well. Keeping Rita confined is a serious escalation, but a solid way to prevent further issues and publicity damage while punishing someone who wronged her.
What's more, let us recall that Hermoine was willing (if conflicted) to mind wipe her own parents "for their own good".
I rather doubt that Taylor will be as understanding as Harry and Ron were in the OTL.
Taylor wouldn't be happy about, but she'd actually probably not be unreasonably upset since it really is to get them out of the country for their own safety; and to prevent potentially important information being leaked from a misstep in keeping to a cover story, or being gleaned from Legillimancy or torture. Not a great situation, but Taylor would appreciate the sheer pragmatism of Hermione's solution, particularly this Taylor.
The entire situation isn't really given much fleshing out sadly, another of Rowling's mistakes in my opinion. We really don't know how that was handled, she might have discussed it with her parents ahead of time so it could've been her parents solution to a problem and we just see Hermione performing the critical step without any other information that we as readers are unaware of. Or Hermione could be fucking with her own memory instead to make it even safer for her parents upon leaving the country so if
Hermione is tortured for information on her family she gives the wrong information unknowingly, while her parents are actually just relocating to France to stay with the Delacours or something and they remember everything instead. She might be extracting the memories she's "erasing" to give back to them later like someone would do for use in a Pensieve, but since it really isn't brought up ever again we just don't know.
