I'd add this the lack of a solid 3rd party developer ecosystem on their Asset Store. The fact that they don't have a subscription model for assets or any support for managing per-seat licenses is ridiculous and is the direct cause of multiple popular assets ending support. It doesn't make sense economically to sell any kind of service on their store.
