Yeah, you're right. When it comes to big business my default is cynical, at the end of the day they're there to extract every reluctant cent they can from consumers. Granted they do frequently provide quality products in that attempt, but more frequently it's about milking the sycophants for everything they can.
In defense of your point though, something like Apple/Google getting into film would change the landscape quite a bit, everything from financing to content would be altered because they may have more unique and accurate perspectives for the audience. That said, I'd prefer big money to stay as far away from creating culturally relevant content as possible.
The problem is big money is already there and it's already dictating what studios do. A tech company frankly has more data available to them about what consumers may want. Hollywood delivers what they think people want with not much data to back it up. I also think the tech companies will offer far more freedom for content creators because the monetary risks as aren't nearly as high.
