Having lived through it, participated in it, and being able to personally contrast people then and now. It's not particularly different, outside of the fact that in the past you had 0.1% of people (if that) using these services, whereas now you have the majority of humanity doing so, so all that's really changed is scale. Beyond that I think there's also a first principles approach one can take. Not only were these services addictive, but so was Facebook (and other similar services) long before 'the algorithm' was a thing. The core interaction is interpersonal, and people simply want to see what other people are saying. We could define that as FOMO, entertainment, or whatever else - but I think this is the shared common core. Even on this site, there are many people who are clearly addicted - myself probably amongst them. Yet there's not even a notification of when something you've written has been responded to, let alone some guiding algorithm. Even having to jump through hurdles to achieve interpersonal dialogue, it is still quite addictive.
