European Alternatives to Twitter/X
Twitter, rebranded as X, is operated by X Corp — a US corporation controlled by Elon Musk and headquartered in San Francisco. Since 2022 it has dismantled its content moderation infrastructure, introduced paid verification, and changed its privacy policy to allow training AI models on user posts without meaningful opt-out. As a US entity, all data is subject to the CLOUD Act and can be accessed by US authorities without notifying EU users or data protection authorities.

Why switch from Twitter/X?
- –X Corp (Delaware, USA) is subject to the US CLOUD Act — authorities can demand your data without notifying EU residents
- –Posts and DMs used to train Grok AI; opt-out is buried in settings and has been silently reset multiple times
- –Advertising profile built from every click, follow, like, and location signal — shared with third-party data brokers
- –DMs are not end-to-end encrypted — X staff and US law enforcement can read your private messages
- –Ireland's DPC fined Twitter €550,000 in 2023 for GDPR data breach notification failures
- –Content moderation gutted since 2022: harassment, impersonation, and health misinformation operating unchecked
Is Twitter/X GDPR Compliant?
Is Twitter/X GDPR compliant? In April 2023 Ireland's Data Protection Commission (DPC) fined Twitter €550,000 for a personal data breach — specifically for failing to notify the DPC within the legally required 72-hour window after discovering that a vulnerability had exposed user phone numbers and email addresses. This fine followed earlier DPC investigations and is part of a broader pattern of GDPR non-compliance by X Corp.
X Corp is a US corporation headquartered in San Francisco. Under the US CLOUD Act (2018), US authorities — including the FBI and NSA — can compel X Corp to hand over stored user data, including data on EU residents, without notifying the affected users or the relevant EU supervisory authority. This creates a direct conflict with GDPR Chapter V on international data transfers and the adequacy standards established after Schrems II.
Twitter/X and AI training: in 2023 X updated its privacy policy to allow using all public and non-public post content for training its Grok AI model. The opt-out was deliberately hidden under Settings → Privacy and Safety → Grok → Allow your posts to be used for training. The European Data Protection Board (EDPB) launched formal inquiries into whether this meets GDPR's standard for freely given and specific consent. X's opt-out mechanism has been reset to 'opted in' multiple times without user notification.
Twitter/X direct messages are not end-to-end encrypted. Unlike Signal, Threema, or WhatsApp (for message content), DMs on X are stored in plaintext on X Corp's servers. Employees with system access and US authorities under CLOUD Act orders can read your private messages. In 2022 Elon Musk publicly confirmed that internal employees had access to private DMs during his acquisition process — an admission that should give EU business users serious pause.
For EU businesses using X for marketing: installing the X Pixel or using X Ads involves transferring EU visitor behavioural data to X Corp servers in the US. The German and Austrian DPAs have flagged this as requiring explicit GDPR consent and a valid SCCs-based data transfer mechanism. X's Data Processing Agreement provides limited protections given US jurisdiction. Treat X as a public broadcast channel, not a customer data or CRM platform.
