More ad tracking too, I suspect. I'd imagine Reddit's audience is fairly heavy on ad/privacy blocking; can't do that in the app.

With autoplaying video with sound, I have to unpause my music after an ad. On the plus side, one brand (AFAICT) enabled comment section on their ad.

They push awards and coins heavily on the app. Like you get constant prompts to spend money on fake karma, digital coins and stuff
