What's the point you're trying to make? That irredeemable companies are a nightmare to work for?
Well of course they are. And just like irredeemable relationships, you need to move on and improve your judgement to avoid a repeat. Bemoaning on Slack achieves nothing.
The point the post you're replying to was trying to make (true or not) was that US companies have this problem unilaterally — so there's no point to trying to avoid companies based on it, as long as the US is where you choose to live.
