The FTC's upcoming 'Click to Cancel' rule is facing legal challenges from three industry groups, including telcos and internet advertisers, who filed a lawsuit in the US Fifth Circuit Appeals Court. These groups claim the regulation is arbitrary and infringes on consumer contracts. The rule aims to simplify subscription cancellations for consumers, addressing deceptive practices prevalent in the industry. If implemented, it would empower users to unsubscribe with a single click, potentially transforming the subscription landscape. The FTC has pledged to impose penalties on companies that engage in hard-to-cancel practices.
