Walmart buying cheap crappy TV brand is antitrust in a world that has many cheap crappy TV brands? At least the Microsoft and IE thing made some sense, it's not like we're hurting for choice here.
Just at the surface level this hurts:
1. Other brands selling TVs in Walmart.
2. Advertisement space will be cheaper for Walmart when they advertise on their own TVs, toeing the line of anti-trust.
3. Companies that offer advertising and data aggregation across TV brands will now have fewer brands to sell on.
4. Fewer consumer TV brands in general.
5. Walmart can adopt a loss lead model, they don't need to actually make money on the TV, they can make it up in 2-3 other places. Similar to AWS and Amazon.
