This is materially incorrect in multiple ways.

1. The Economist’s reporting is widely recognized for its absence of bias.
2. Leaders are not opinion pieces, they are brief overviews, hence why they seem like “truncated versions” of articles.
3. The “snippets of opinion” to which you refer are reporting on public opinion. I thought that was obvious.

This is false. It still has areas in which it could improve, but it is a thousand times better than twitter.
