Those examples aren't entirely invalid, but in one case of one of them (Purdue) they are facing legal jeopardy for their actions including a $270MM settlement in Oklahoma alone. The other company was founded 400 years ago, relied on letters of marque issued by (you guessed it) governments, and is no longer a going concern.

The thing about governments is that they have basically zero accountability to anyone except a better-armed government. We talk a good game here in the US, but it's certainly playing out differently.
