Amazon and Apple are undercutting Hollywood and losing money. They're subsidizing their Hollywood efforts with funds from unrelated business units (hardware, grocery stores, primary care doctors, etc.) You can get cheap (free) entertainment if you subscribe to Amazon Prime shipping, so why spend money on the competitor's product if entertainment is (at some gross sense and scale) fungible?
The thing that needs to be broken up is the ability of these giants to subsidize moves into healthy existing markets or even nascent markets. They push out the incumbents with their massive cash hoards gained from unrelated business unit activity. They don't even try to profit at first until they've captured the market and suffocated the existing players.
It's unfair that Amazon and Apple can make movies, buy out James Bond, Lord of the Rings, etc. off of their trillion dollar market caps, iPhones, and AWS profits. It's unfair that they can plaster free advertising on the side of their delivery vans or get free ad placement front and center in their App Store. That costs everyone else millions of dollars - a large percentage of the unit economics. Big tech has every advantage and is literally murdering entire markets with these insane, unfair advantages.
These giant companies are like an invasive species. They're like lionfish moving into the Caribbean, killing all the local fauna. No natural predators. Complete decimation of the local ecology.
Their behavior disconnects innovation, healthy and rational market monetization, and the actual rewards that should go to the investment and labor capital pioneering those areas. Institutional giants are snuffing out anything they see that they can expand into.
Big companies need to be broken up for the sake of healthy markets and innovation. Big companies are gravitational singularities that distort everything.
