Not really. There are likely some non US citizens employed, but "relies" is utterly ridiculous. I live right next to the largest shipyard in the country, and the VAST majority of the workforce is made up of US citizens. There are exactly zero non-us citizens employed building ships for war.

It seems you are grossly out of touch with the actual American workforce. We have tons of welders.

Oracle still does the same thing. You can download their database (full enterprise edition) for free, for development use.

However, this does not grant you a license to use the database in a production environment (say, powering your Config Management software).

The new "free" versions grant you the license to use it in production environments.

I imagine IBM's new free version is sort of the same thing (I read the article, but have not yet reviewed the license).
