I suppose everyone does. It would be one hell of a way to save face.
I do not know much about how others see it, but I hope that it is not a hoax.
Sadly, the chance that it is a hoax is relatively high.
Offering it has a few drawbacks for CO/PDX but not so many. Sure, they have to offer additional content for "free." On the good side, people may not give up on this brand.
Currently, the trend is this:
CS2 has a 56% rating on Steam, and the last word (the DLC/content pack) has a rating of 10%.
-> This is a very strong negative trend with little hope.
The Ports DLC talks about 100 buildings, we already know that if PDX sells it for 10 bucks, ratings of around 10% are expected.
-> The active player base will quickly get smaller; future DLCs, even if they are great, will not achieve many sales due to the low number of active players.
If CO can fix the first DLC and bring in hope, fanboys may give CO and this series another last chance. In that case, it is financially worth it.
Is it likely? No, because Paradox history with other games suggests a different outcome, but it is not impossible. It would be the right thing to do if PDX and CO really want to save the series.
Continuing the old strategy is unlikely to bring the game back.
