One problem with centrally produced and distributed software is that a small subset of users demanding certain features results in feature bloat for everyone. Costs for all features are shared by all users.

Probably one way SaaS companies will adapt is to break up their offerings into more modular low cost components. While many customers will end up paying less, the addressable market will probably increase because of the new low cost options.

To a degree but most enterprise focused software usually has differential pricing. Often that pricing isn't public so different companies get different quotes.
