"We reserve the right to change the Terms at any time, but if we do, we will bring it to your attention by placing a notice on the website, by sending you an email, and/or by some other means. If you don't agree with the new Terms, you are free to reject them; unfortunately, that means you will no longer be able to use Substack. If you use Substack in any way after a change to the Terms is effective and notice has been provided, that means you agree to all of the changes.Excerpt from Substack's Terms of Use
1) REGULATORY LANDSCAPE: Unilateral modification clauses in consumer contracts are subject to scrutiny under consumer protection law in multiple jurisdictions. The EU Unfair Terms Directive may render unilateral modification clauses unenforceable against EU consumers unless the right to modify is for valid reasons and adequate notice is provided. In the US, the enforceability of unilateral modification through continued use acceptance is generally upheld but varies by state and context. The FTC Act is broadly relevant. 2) GOVERNANCE EXPOSURE: Medium. The absence of a specified minimum notice period before changes become effective creates operational uncertainty, particularly for creators and organizations with revenue-dependent platform relationships. Notice via website posting alone may be insufficient to establish actual notice under some jurisdictions' consumer protection standards. 3) JURISDICTION FLAGS: EU consumer protection law imposes requirements on unilateral modification clauses including valid justification and adequate advance notice. California's contract law requires that unilateral modification be communicated in a manner reasonably calculated to provide actual notice. UK consumer regulations may similarly impose constraints on unilateral modification in standard form consumer contracts. 4) CONTRACT AND VENDOR IMPLICATIONS: Organizations that have integrated Substack into operational workflows should establish a process for monitoring Terms changes, as continued platform use after a terms amendment constitutes acceptance. B2B contract review should assess whether the unilateral modification clause is consistent with the organization's contracting standards and risk tolerance. 5) COMPLIANCE CONSIDERATIONS: Legal and compliance teams should establish a monitoring procedure for Substack Terms changes given that changes become effective upon notice and continued use. The document states that notice may be provided by email or website posting; teams should ensure Substack communications are monitored by appropriate personnel.
