What's really happening is that China and India have been beating them on price for years now and are currently buying out European production capacity, so those factory owners are just pulling every lever they have to stay afloat.
It has nothing to do with decarbonization and everything with them having no idea how to compete. It's all the same across your northern border with coal - the coal miners want a graceful phase out because they understand that Australian pit-mined coal is cheaper despite being hauled across the world, but the owners want to keep the status quo and associated government subsidies.
"It has nothing to do with decarbonization and everything with them having no idea how to compete."
So they lost all the ideas since the 1980s or so, when they were top of the heap?
Maybe, but increasing cost of inputs has more than nothing to do with economic balance of any business. Even regular households feel the increase in heating and electricity costs. A factory which needs orders of magnitude more energy will feel them even more.
Cheap energy is very important to any industry, no way around it. That is why China builds so many power stations.
