When the entire world has been built around requiring you to use petroleum to go places and build certain things, and requires you to use certain software to interact with everyone, I have sympathy for users whose hands are often tied from the get-go. I can't blame them when "the system" (a reductive phrase, but it works for this response) is setup as such.

That there's demand isn't necessarily the fault of the user, in many cases it's the fault of industry. At this point, at least for petroleum, it's a feedback loop - we built infrastructure around it, people became dependent upon it because alternatives are limited, the dependence creates demand, and that demand is used to justify continued production.

The petroluem industry then just has to work hard to squash alternatives, as it very much has, thereby leaving the user with little to no choice.
