This article sounds like someone has an axe to grind. Blaming extremism on a handful of companies sounds awfully convenient and completely ignores the motivation for extremism in the first place. Next they blame transportation companies for making it too convenient to travel. Those things are just the result of governments pampering to capitalism. Customers want a service and then a company (or a radicalized activist) provides it. The problem is that governments let themselves get manipulated by large corporations and the wealthy instead of listening to the rest of the population. The end result is an environment in which companies are allowed to engage in destructive behavior.
