How is that not an anti-trust issue?
Because we live in the bad place. Conservatives are unlikely to pursue anti-trust unless they're using it as a tool to hurt out-group (eg: they might try to break up an organization they perceive as being too queer).
We don't have a strong left in the US. You get glimmers every so often - Lina Khan was trying to do anti-trust work, but then trump returned and that's all moot.
A lot of problems would go away or be less bad if we stopped letting power consolidate. Unfortunately, this is the bad place.
