I would have thought exactly the opposite: that these groups would adopt the strategy of portraying these types of issues as being primarily about “individual responsibility” knowing that the only way to actually change things is collective action.

Policy makers duped consumers into sorting plastic waste and even go as far as put a plastic tax on consumers, while the majority of plastic waste comes from the industry, and is burned as fuel and greenwashed by being called "recycled energy".

Policy makers and the industry successfully shifted the blame on the population and people are even ashamed of having a vacation these years, because other duped individuals keep harassing them in the name of capitalism.

You seem to have no understanding of the severity of things.

The only way to make a real change would be to correct the incentives. This can be done via legislation & policy but an individual can’t do it alone. I suppose an individual could change the incentives for one or two companies (e.g. violence against a decision maker) but it wouldn’t change the economics of doing business.
