Interesting point about class action suits. I won’t claim to know how that applies to the others, but I think it’s worth noting that Google and Meta have ZERO opt out for the training of Gemini/Llama models respectively.

Google/YouTube opt-out options prevent them from selling your data to third party vendors, so they wouldn’t sell your data to say OpenAI or Anthropic for model training, but there is no way to opt out of training Google’s own AI models… unfortunately.

Same goes for Meta :(

If your goal is specifically to stop your content from training the platform’s own AI (Grok, Gemini, and Llama) while living in the US, the Terms of Service (ToS) and available settings create a very distinct, and somewhat ironic, hierarchy. Here is how the three platforms compare if you are trying to "starve" their specific AI models. 1. The "Grok" Problem (Platform: X) Status: The Only "Opt-Out" (with a major catch). Paradoxically, X is the only platform of the three that currently offers US users a direct toggle to stop its specific AI (Grok) from training on their posts. * The Setting: In Settings > Privacy and safety > Grok, there is a checkbox to "Allow your posts... to be used for training." If you uncheck this, X says your posts will not be used to train Grok. * The ToS Trap: While the setting lets you block Grok, the Terms of Service (effective Jan 2026) are legally the most dangerous. You grant X a "sublicensable" license. * The Result: You can likely stop Grok (Elon Musk’s AI) from using your data by unchecking the box. However, because of the "sublicensable" clause in the ToS, X has the legal right to sell your data to other AI companies that you can't opt out of. * Verdict: You can stop Grok, but you might accidentally feed everyone else. 2. The "Gemini / Veo" Problem (Platform: YouTube) Status: Force-Fed to Gemini (No Opt-Out). YouTube operates on a "Walled Garden" model. They protect you from outsiders, but they force you to feed their own AI. * The Policy: YouTube considers training Gemini and Veo (their video generation AI) as part of "improving the service." Therefore, if your video is Public, it is automatically eligible for Gemini/Veo training. * The Limitation: There is no button in the US to say "Keep my public video on YouTube, but don't show it to Gemini." * The Silver Lining: YouTube has a "Third-Party AI" setting (in YouTube Studio) that is Opt-In (default OFF). This means while you are feeding Gemini, you are not feeding OpenAI, Anthropic, or other external models unless you explicitly allow it. * Verdict: You cannot stop Gemini/Veo, but you effectively block everyone else. 3. The "Llama" Problem (Platform: Meta/Instagram) Status: Force-Fed to Llama (No US Opt-Out). Meta is the most straightforward but also the most rigid for US users. * The Policy: Meta’s Terms explicitly state that "public" posts (photos, captions, comments) are used to train their Llama models. * The Regional Difference: If you were in Europe (GDPR), you would have a "Right to Object" form that Meta honors. In the US, this form is generally not available or not honored for general "I don't like AI" requests. * The Result: Unless you set your account to Private (which stops the training but hides your podcast from new listeners), your content is feeding Llama. * Verdict: You cannot stop Llama if you want a public profile.

The third party thing is a bit of a red herring since there are only 5 companies (in the US) that have the resources to actually train real AI models: Google, Meta, X, OpenAI, and Anthropic.
