Do tech giants control public discourse through algorithms?

1) What kind of claim is this?

This is a control claim about platform influence.

2) What context is assumed or missing?

Details of algorithm design and regulatory oversight are not described.

3) What has to be true for this to work?

Algorithms would need to shape exposure strongly and lack transparency.

4) When would this not hold?

The claim weakens if users and regulators significantly limit platform power.

5) What follows if we accept it?

Public conversation may be seen as centrally steered.
