I think it's political, but is based on three observations.
1. The FANGs are making lots of money, and a significant fraction of people think if a company is making loads of money, it is doing something bad, or at least exploitative.
2. Old media companies are suffering in the internet age; many are struggling for survival, but people want media to survive.
3. News Corp was started in Australia, and has good lobbying power.
If these three things are true, to a politician, it may look reasonable to take money from the FANGs and give it to media companies.
(If this crosses the political line for this board, let me know, and I'll be happy to delete the post. I just don't see an explanation for the question that doesn't involve politics.)
