It's pretty simple. Reddit as a company seems to have been on a path for years where they have done everything they possibly can to make the site more corporate at the expense of Reddit as a community.
I've been on Reddit for years (I deleted at least two accounts before sticking with my now 14-year-old account). To put it in context, my Reddit account is older than my child, who has his own Reddit account.
There were a lot of things on Reddit that I found annoying but it was easy to ignore. I was saddened by the way they fired Victoria and unfairly blamed it on Ellen Pao, and the effects of those decision s including the noticeable degradation in quality and corpoatization of AMA posts.
I also hated how blatant advertising and astroturfing kept showing up more and more and did not like the way practically everything turned into politics and divisiveness in a more recent era.
But again, most of that was pretty easy to avoid and I could just stick to my little niche subreddits that I liked, ignore the rest of the content, and view the site and a format I like because I could use a third party app. I never really cared for new Reddit and especially hated the official Reddit app, and with that being gone and ads and chat being forced on me, I'm done with it.
It is a religious thing. I grew up fundamentalist Baptist and then softened up into the Evangelical world before leaving Christianity behind, and this was very common for both parents to use to get reports and see if their children were looking at porn and for men who had gotten caught or admitted to struggling with porn or cheating to have another man as an "accountability partner" and give access to his internet history through this program.
The software came up during the Josh Duggar trial because his wife had put it on his computer before either his cheating or his other inclinations became public knowledge.
