It doesn't state anywhere that they were "fake"!

In fact, it has become increasingly common for federal agencies to
adopt the public relations tactic of producing "video news releases"
that look indistinguishable from authentic newscasts and, as
ready-made and cost-free reports, are sometimes picked up by local
news programs.

This is done routinely by many organizations and "interests" not just the
government. The TV media love it because it is "ready to air" with no cost
to the media outlet. If you have watched a "medical" news bit you have
seen a "video news releases" by a health organization with their own agenda.
Free advertising with the media sometimes airing them with little to no
verification.

It is very prevalent in the TV media business.
Sometimes you may not even realize what you are watching.
