There are now deterrent nets and misters, I suspect the geese wouldn’t figure it out without them

What about their reply made you think they held this opinion? Genuine question, it doesn’t read that way at all to me.

I enjoy not having corporate censorship deciding what I can and can’t see or say; not that I comment or post that much.

I believe they’re saying the stuff in the parentheses are things the US is doing

Maybe a slightly different example will help understand the logic?

Let’s say NewsCorpA likes Trump and Spacey.

NewsCorpA publishes their usual stuff saying they’re both cool and good, but one day they post an article saying Trump did something bad. Because they have every reason to like Trump it seems more likely to me that the article has a genuine criticism (not to say their reasoning is good. E.g. He’s not racist enough), but that doesn’t have any bearing on the other, usual, articles about Spacey.

In other words it’s kinda the inverse of “if someone hates someone and says something nice about them, it’s probably genuine” so kinda “if someone likes someone and says something bad about them, it’s probably genuine”
