TL;DR: Reddit is removing the option to opt out of ad personalization, targeting ads based on user activity. Some specific ad categories can still be limited, but there’s no more opt-out option.
Conversely, I’m so opposed to the enshitification that I’ve carefully tailored my internet usage to places that aren’t shit and have no prospect of becoming shit, like Lemmy. Since I don’t even have the motivation of not supporting an evil company, I’m more addicted that ever.
