why are they so angry?

I just got a couple threats via email from big oil companies who are trying to keep this secret from you.

Actually, one is a cease-and-desist letter.
The other is a downright threat.

They don't want you to find out how you can use water
to save up to 60% because that would put them out
of business... So they're trying to shut me down.

And that means your time might be limited.
