the trade off is either you make your own hardware, or make exceptions to integrate with other OEMs, which causes the fragmentation problem that security vendors exist to provide solutions for. Apple doesn't have that fragmentation problem, but they also don't have as rich an enterprise ecosystem. Android is the definition of a fragmentation problem, where instead of resolving it, Google manages it and calls it an ecosystem, and they're right. Fragmentation makes consistent governance/security impossible, but the heterogeneity also limits the scope of incidents. Apple balances its greater monoculture risk with deep control of the underlying hardware, to where as a user or developer you're only ever interacting with a very, very high level abstraction.
