No. Small publishers have no choice. They have to be where their readers are. All they can do is try to diversify as much as possible, but it won't mean a whole lot if one of the world's oligopolists cuts them off overnight.
Exactly this. The benefit of small newspaper services is just too small for most of their readers to bother making sure to actually receive the news.
If they are gone, other content will fill the gap. That's pretty bad for those current content creators, sure. It also enables a local news revival as soon as people realise that there might be huge value in some forms of local publishing.
