I would actually make the argument that the heart of the problem here is not either about fans, as the article claims, or production companies being exploitative cowards, as some of the comments are claiming. The heart of the problem is the increasingly eroding privacy we are seeing in the modern age.
There's some people in the comments saying "fandoms have always been like this" and others saying "No, it's worse than it was." And both are to some extent right. Fans (or at least a small percentage of fans, and the larger a fanbase gets the larger a group this will describe) have always been Like That; but they did not always have the level of access to creators and actors that they have now.
The notion that a performer needs to be constantly available to public scrutiny, that their personal information should by default be available to any rando with google, is pretty new. It used to be that actors would only be expected to engage with the public on limited, specific, and controlled occasions, usually with security provided. Now they're being asked to rawdog exposure to the mob 24/7 on their own.
(Also, production companies have always always always been exploitative cowards, just to get that straight; reading the biographies of literally any actress from golden Hollywood years makes that clear. It's just, again, more public now.)
There has also been a negative feedback loop as fandoms come to realize that the constant access they have to creatives increases their leverage and power. It did not use to be the case that this was so; fandoms pre-internet largely worked under the assumption that they didn't really have any meaningful way to contact or influence the publication houses. Even if they sent a letter or a campaign of letters, they wouldn't even know whether the letters were being received or read unless the publishing house chose to respond. So, without that expectation of access, the drama usually stayed internal. Nowadays, with constant immediate feedback from creators and publishers, fans are ever more incentivized to act out to try to push an agenda, get attention, or just vent whatever is going on in their lives onto a face contractually obliged to be friendly to them.
