I used VaderSentiment (https://github.com/cjhutto/vaderSentiment) for sentiment analysis.

It's not a perfect solution, as I'm sure some of the discussion on these companies is loaded with jargon that wouldn't be interpreted accurately by a general sentiment analyzer.

In my view amazon is being fairly honest in comparison to other scumbags: yes they mistreat their workforce and cheat on reviews, but it's all part of the game, they didnt create the game.

Looking at the colouring (that reflects sentiment, right?) Amazon is pretty unpopular - and taking a rough mean over the past few years, similarly disliked as FB.

Or am I interpreting it incorrectly?
