I'd say the owner is making it worse, and it's not the responsibility of people to invest more of their effort into his platform when they can build up something they can feel way more ownership of. Bigger isn't always better. The people who would miss out on things they don't want to miss out on aren't switching, but I haven't seen a single person who did switch expressing regret. Logically speaking, that's not what you see when people do something motivated purely on emotion ;)
