Layer 2 options exist, but the majority of stake is in layer 1 - with layer 2 posts also accruing (potentially) layer 1 tokens. There is no reliable layer 2 token for either general content or 'truth' content that is beyond the focus and reach of the current layer 1 large downvoters yet, so most content creators currently end up having a focus on layer 1. There are plenty of people who don't even understand how layer 2 works - please remember that most people don't have the time/focus into things like Hive that perhaps you and others you speak with do.
I personally had built a social network before Steem existed (more than one actually) and I built it with the intention of solving the problem of my own online censorship (which was real and unusually high even back then.. I have consistently been a top performing profile on any network that supports free speech and consistently not done well on silicon valley, controlled networks). Anyway, my intention has been to relaunch my own site as a Steem (now Hive) community, but SMTs took forever and Hive Engine has a high cost to entry that I personally cannot afford due to personal issues in my life atm. However, I am working on a layer 2 token as part of a team, which would have already been live except for factors outside of my control. Currently, I am looking to help the SPK network to lower the cost to entry and at that point all of these reward pool problems may be resolved, as communities will be empowered to action a 'Justin Sun Defence' strategy and just fork their community and coin if someone comes in with nefarious intentions.
I have said all of this multiple times in the past few days, both in the 3speak community session and in my posts and comments.
