@matthew_d_green It starts out being true because the upstart has to be competitive with alternatives. Once they get market dominance they can use network effects and lock in to maintain it, so less urgency to improve the product/service. This is when you start to see new features/UI revamps that no one asked for and everyone dislikes.
With decentralized systems and open protocols ppl can easily switch to competition and do. With free software they can even undo/fork anti-features.
