The goal of the LSP Spec is to create an open system and avoid lock-in. Hopefully this plays out. With that said, capital intensive markets tend to be more centralized than non-capital-intensive ones.

One factor that might offset some of this tendency to centralize is that there are diminishing returns to increasingly massive LN channels. A 10BTC LN channel isn't all that useful if the average payment size is 10k sats. Individuals need many channels in order to reach the full network, which means that smaller players can enter the LSP market and sell small to medium sized channels.
