"a braver film would have addressed this somehow. Samantha is a slave." I don't think Samantha is a slave. Note that Theodore is not shown paying for Samantha.

"a braver film would have addressed this somehow. Samantha is a slave." I don't think Samantha is a slave. Note that Theodore is not shown paying for Samantha. He could as well have partaken in a free beta program. She also asks for time for herself, does not sound slaveish to me. There were many places where the story could have gone, but Jonze decided not to go there: privacy, hacking and trust, malfunctions, AI doing stuff for you that you did not explicitly asked for and Theodore suing the company for that. Jonze simply decided to accept Samantha as a real person in a love story, and go from there. I don't agree with you that "Her" is not a brave film just because it did not raise issues that you had in mind.
