Regrettably, by posting your work on Wikipedia, you relinquished your copyright claim.

And Wikipedia is not a US company, and has no bearing on US copyright law.

Common law copyright will always exist for provably original content, regardless of distriibution.

But a new company is not sourcing the information and claiming it as fact.

As more of our time is spent on screens, we are becoming the lifeblood of technology created to entertain us.
