It's a tricky thing. This article seems biased toward the assumption that all accusations are valid, but you can't assume that in real life. The article actually does bring up the Amber Heard case, but ignores the fact that Amber Heard's accusations really were defamation and simply talks about how the fact that she lost will embolden other people accused of abuse to defend themselves as well.
The article says:
Being labeled as a harasser or rapist carries more reputational damage than it used to, thanks to #MeToo. This is a way for abusers to try to claw back that lost status.
Sure, but it's also a way for the falsely accused to clear their names.
There's likely no "perfect" solution for any of this, but IMO this sort of thing is just further pressure to try to make the justice system work better in general. If it wasn't so burdensome defending yourself against lawsuits then there wouldn't be this problem with "victims who can't afford to speak out."
