Is this for sure all paid with tax money?

Here in the alps, if you have an injury hiking and need a helicopter ride then you are required to pay for the ride (normally a few thousand euros). I assume it's the same if you're lost.

And I would assume it's the same on high sea...

yes, same in Canada afaik. seems quite plausible to me that some of these bills will be sent to OceanGate, we don't know. ofc their ability to pay is another question.
