Copyright and licensing uncertainty could hinder that, and the status quo today in many places is to not treat training as copyright infringement (eg. US), or to require an explicit opt-out (eg. EU). A lack of international agreements means it’s all a bit wishy washy, and hard to prove and enforce.

Things get (only slightly) easier if the material is behind a terms-of-service wall.
