Sure, but then that’s an even worse enshittification if they do make it random.
The mandatory add wait-time will stop people from seeking through videos organically. Yet another thing that makes it worse for everyone.
And even then, it should still be possible to detect which frames are part of the original video and which are not, either by detecting original video frames, or building a database of ads and detecting them within videos.
The fact that lots of people still use reddit is just due to inertia. Platforms don’t die immediately overnight. Digg still exists. It still calls itself “The homepage of the internet.” The process of transitioning to a federated internet is going to take many years.
Reddit is still dying however. There’s been a marked drop in the quality of posts over there, and they’re harder to access, now they’re doing an exclusivity thing with google which is also enshittifying massively. That is making it less and less appealling over time. It won’t last forever as a culturally relevant site.
