I'm sorry but if the companies bottom line depends on forgotten subscriptions you dont get to cry foul when your dark practices need to be removed.
Nearly any mandated changes to nearly any company's software no matter what business they are in will incur costs. The FTC is required to take extra care when regulating in the case when those costs will be high.
In MAGA terms - if your business cannot survive in free market competition without scam schemes - it’s “unamerican” and shouldn’t be a business.
I would agree with this argument. After all, you have to staff the customer service phone lines now to cancel service. It follows that presumably customer service's capacity to retain customers/revenue is profitable after factoring in costs for their wages and overhead. Dark patterns may cost money vs light patterns, but they also may have more net profit.
There are numerous states with an existing "click to cancel" regulation. If you're compliant with those states then that implementation was federally compliant as well.
The only huge cost is a drop in revenue not an increase in cost.
