In my mid-40s and never have gotten a cavity.

I feel a part of it is similar to anger of the natural process of grieving. Many of us spent years contributing to the platform and enjoyed just spending time with other like-minded members of subreddits. I personally loved reading the chains of comments. Reddit was a great source of pleasure; a place for sharing humor, frustrations, and other random cool things. Much of what made it enjoyable, including he third party apps, was taken away in a fashion that felt like the user base was betrayed, hence the utter vehement expression of some former users. It will pass in time.
