But Wish is in a retailer vs Shopify as a platform. I Highly doubt wish has the same value. In fact, I don't know a single instance of someone shopping wish and being satisfied. Someone will buy it, it'll probably be way over valued, and it will eventually drop back.
Shopify is a service provider, it's not a platform because it doesn't control the relationship with the consumer. Wish is an aggregator on both sides and that's why it's a platform.
