This provision establishes a unilateral amendment mechanism under which Twilio can modify agreement terms with 30 days notice, and the customer's continued use of services constitutes binding acceptance of those modifications. The carve-out for law, regulation, or telecommunications provider-driven changes permits immediate or shorter-notice modifications in those circumstances.
Interpretive note: The enforceability of continued-use acceptance for material contractual changes varies by jurisdiction, particularly in the EU where unfair contract terms frameworks and GDPR consent requirements may constrain how changes to data processing terms take effect.
The updated terms establish a binding arbitration requirement for users domiciled or registered in Mexico, replacing prior dispute resolution procedures. Under the revised Section 10.5, Mexico-domiciled users must first engage in good faith negotiations with Segment for up to 30 days, and if unresolved, disputes proceed to binding arbitration administered by the Centro de Arbitraje de México (CAM) in Mexico City before a sole arbitrator, with both parties splitting arbitration costs. Additionally, the agreement now explicitly carves out Mexico's Federal Consumer Protection Law (Ley Federal de Protección al Consumidor), stating it does not apply to this commercial agreement. Mexico users also face a new obligation to comply with anti-money laundering and anti-corruption requirements under applicable Mexican law.
