The whole story you're missing on BSV is that once the chain way beyond anyone's tolerance to sync anymore it was essentially controlled by a monopolist miner, Calvin Ayre the sponsor and co-conspirator of Wright,  and they used their control to force hard fork consensus rule changes onto the system like "asset recovery" -- basically allowing themselves the ability to steal any coin on the system whenever they want.

So like, sure spam bad or whatever.  But so what, who cares?  There is a *reason* the bloat is bad-- and that's because users autonomy to reject rule changes depends on the ability to run a full node being a practical choice.
