The big issue with opinion sections is in the era of newspapers, it was obvious you're reading the opinion section. You might get a tease on page 1 to "Read Bill Clinton's views on Bernie Sanders' presidential chances on page 4" but it was clearly in the Opinion section, separated from 'real' news.
In the era of online news, opinion sections are blended with news.
Even The Guardian falls prey to this: go to https://www.theguardian.com/. Click the Opinion tab. Click any of the opinion pieces. The primary navigation reverts to having 'News' highlighted.
Worse, in reader/mobile view modes, the label "Opinion" does not show anywhere.
It's not a great app, but the one thing it gets right is behaving quite like a newspaper - even down to navigation to select which of the past 6 days' (plus today's) editions you'd like!
(What it gets really wrong, and refuses to accept is a bug every time I report it, is that when the edition updates at 9am/noon/5pm/midnight if you have an article open it randomly jumps to a completely different article that now occupies the spot on which you clicked to open the initial one.)
