Because the corporations are saying it is an increase in costs that are driving higher prices, not demand. And the price curve for things like "eggs" is not being driven by demand.
I have a hard time believing this is supply-side inflation. Are they saying that multi-national corporations are inflating their own prices so-as to invoke cost-push inflation so that they can profit on the back-end? If that's what the EU is saying (which is what you're implying) than they're insane conspiracy theorists. markets aren't centrally planned processes, especially markets as complex as the EU's. Chances are it's demand side inflation, which is exactly what the US has. The US had a massive recession in 2007 and they inundated corporations with bailouts yet this did nothing to spike inflation. When the US pumped trillions of active currency into the economy they triggered demand-side inflation (https://www.bloomberg.com/news/articles/2022-08-24/demand-su...). How is the EU any different? They too pumped excessive amounts of currency into their markets (https://www.consilium.europa.eu/en/policies/coronavirus/covi...).

It could be when all the brands are owned by a couple of corporations, which are chaired by a couple of large investment firms.
You know for a fact that big tech was doing a no poaching agreement in 2005, but can't wrap your head around the fact that corporations can collude on a price hikes in 2023?
You picked just about the worst example to make your case. Egg prices Spiked to huge numbers because of large culls of egg laying hens then fell back down. They didn't fall all the way back down because customers are now willing to pay higher prices
no don't you understand, the egg producers just became more greedy for a bit and raked in extra profits, then decided to become less greedy! Get out of here with your important context!
