Yes. Except they are attempting to make the claim that protesters are interfering with federal operations, which is a crime. Therefore, they can try to make the claim that they are only investigating potential involvement in a crime, punish you, and file it under a violation of the terms of service for precheck and global entry. IANAL, etc, but this seems to be the strategy.

I don't think that terms of service can override the constitution, in any case
