They do. Some other states already have easy cancel laws.

If a business is so small that this would be hard to manage, then they're probably not big enough to have MBAs rubbing their hands and implementing impossible to cancel systems. If a business is so big that it can afford to pay call centers to deal with their intentionally Kafkaesque cancellations, then they can afford to deal with the regulations. They can't as easily afford to lose 12 million customers.

Easy canceling is far, far easier to make than the stuff these regulations target. No honest mom and pop shop is losing sleep over this.

The federal government is too dysfunctional to pass this sort of obvious legislation. They protected their video rental records within a year after Bork was smeared. Dark financial patterns? That's just too hard to do.

If the federal legislature is not elected on a platform having to do with quality-of-life issues then obviously they will not work on that or be held accountable to it.

Amazon would love it, as it would begin to crush smaller retailers and they have the capacity to handle dealing with various law differences.

PA is also the 5th most populous state. 90% of US states are smaller in population.
