Think about it: Those giant companies don't want competition. They don't want some upstart to threaten their dominance.
Why wouldn't they support more and more restrictions on business?
The mom-and-pop stores, which are unwanted competition to them, those small businesses can't meet all the regulations and shutter down.
However, the Big Businesses have tremendous wealth and can meet these new regulations as a small price to pay to shut out potential little rivals showing up.
Kind of like why Phillip Morris supported regulations on tobacco companies a few years back... they knew they were the only ones who had the resources to follow a new law..
