Actually, since the Internet began to be public domain, physical newspapers has lower and lower sales. Since people can find the news online. This is one reason behind ads online.

Today, many local areas have nobody that works as a journalist, no local news=local politicians can do whatever they want without anybody question them.

So, what do you prefer? A community that has journalists asking the tough questions, digging for dirt or a community where corruption can flow free?

Support your local newspaper/news station with a subscription and use adblock.

For mobile I would say adding blocklists in the router.
