It’s just human nature, simply complacency. At times when doing business is generally more difficult, why produce more when you can produce less and charge more? On a long enough timescale in current conditions, every business will do it eventually.
This is what has just been happening with Cal-Maine eggs for example. Exaggerating about supply chain pressures and arbitrating prices to cover production slowdown was just the easiest thing to do in the circumstances. It isn’t until much later when the earnings reports come out with no substantial supply chain interruptions to mention that people start to realize what’s going on, and by that point they’ve already siphoned hundreds of millions more from the public than the circumstances warranted.
Egg prices are dropping now. Why? There’s been no recent change in cost indicated in Cal-Maine’s production. The only recent news regarding their operations is the release of that earnings report. It’s as if public knowledge about their record profits is somehow affecting the price of the commodity they produce?
Also in Aus here, using ISP DNS, not blocked. I think what you generally find is that most ISP’s just don’t do the DNS blocks, even if they’re required to. Like you said, it’s very easily circumvented and also it just doesn’t lead to any measurable outcome other than the ISP customer’s dissatisfaction in some cases. It’s probably more profitable to retain the customers and deal with whatever regulatory blowback.
