People are not so much tuning out the news as they are tuning out the narrative pushed by the likes of the Guardian et al. The old Soviet riff about there not being any truth (правда or 'Pravda' , the newspaper of the Central Committee of the Communist Party of the Soviet Union) in the News (известия or 'Izvestia', the newspaper of the Supreme Soviet of the Soviet Union) nor was there any news in the Truth holds true for most of the legacy news outlets out there. The clear bias shown by the Guardian and similar outlets has made them close to useless as a source of news.
There are plenty of alternatives now which are not under control of the legacy publishers. Most of these are just as biased as legacy publications so following 'alternative news sources' is not a panacea for getting closer to the truth. You need to follow a number of outlets with different - and often opposing - biases to get a wider picture. RSS feed readers do wonders here but it still can take quite a bit of time and effort to separate 'news' from 'narrative' no matter the source.
