I think there's a legitimate difference though, because with TV news, it was still trained journalists who were doing the interviews. What we have now is a situation where the biggest platforms are hosted by people who are not actually going to hold politicians to account in any way, and couldn't even if they wanted to, because they don't have the training or editorial standards to do so. This isn't just a Trump thing btw. It's not like Harris wasn't appearing on huge podcasts that would give her an easy ride.
We used to have the same criticism when David Cameron would appear on This Morning or The One Show instead of Newsnight or Question Time. Everything is just so stage managed nowadays and even press conferences have plants in them selected to ask low-ball questions that allow the politician to bang on about some key policy. The average Premier League manager has more accountability to the press than the President or Prime Minister these days.
