"Mars Water" - The NASA PAO in action

This annoyed me so much, that I thought it deserves a separate thread
due to its implications in regards to the NASA PAO:

This isn't the first time we've heard the "water flowing on Mars" story.
Back in 2000, NASA was showing pictures of gullies in craters taken by
Mars Global Surveyor and saying they were caused by liquid water flows:

Then afterwards, dissenting voices arose to this interpretation:

But Mars Global Surveyor has now croaked, and as a going away present,
NASA has given it credit for finding the same thing again:

Even though in all likelihood all it's found are dry ice or soil
deposits from subsurface liquid CO2 escaping.
Notice how liquid CO2 doesn't even get mentioned in the press release?
Notice how the new "water" flows are still coming out from deep
underground on crater walls...where liquid CO2 could exist?
And at latitudes above 30 degrees, where liquid water would have a
harder time existing than at the warmer Martian equator?
