Google relies for a great deal on advertising and gathering user data, unlike Apple. On top of that they don't have tight control over who sells Android devices, nor do they appear interested in doing so. Sadly it doesn't look like they're interested in delivering better data protection for their users.

Google sells their own phones and could introduce hardware driven indicators next to the camera and microphones for when they are on if their goal was not to be evil.

It is a general problem that no one makes strong claims about indicators, so making a software driven camera led is not bad for a manufacturer's reputation.
