Tech giants reject telecoms' blockchain spam-fighting plan for messaging apps, citing technical hurdles.

Technology companies like Google and Meta have declined telecom operators' request to regulate OTT messaging apps, such as WhatsApp and Google RCS, through a centralized blockchain system to fight spam. Tech firms argue that this is not feasible due to technical and operational challenges and the non-interoperability between telecom and OTT services. They suggest telecoms focus on AI innovations to reduce spam and compliance costs instead.
