There is also a difference between a clickbait headline and a headline that genuinely engages someone. Something like "Unexpected discovery of sulphur crystals provides hints about Martian past" provides vastly more useful information and will probably be more appealing to people who have at least some interest in science. (Or at least rock collecting!)
At least in my case, I decided to read the comments here before even considering a look at the article. Not only did the idea of a "surprise" leave me thoroughly disinterested, but I have been bitten by NASA's hyperbole often enough to be hesitant about pursuing a clickbait link. Which is sad, because planetary science is interesting and the article itself wasn't that bad for something directed towards a general audience.
Personally, I find clickbait titles lends an air of tabloidness to a publication. I wouldn't be surprised if that is a common feeling. I will also actively avoid, clickbait titles even from trusted sources, simply because it would be detrimental in the long term. Granted, I suspect the active avoidance part is an unusual behaviour.
I don't like watering down the defition of clickbait to mean any headline that gets the reader to click on it. That sort of definition is mostly an excuse for bad behaviour (e.g. misleading the reader).
The public, for the most part, stopped caring about NASA after the US stopped going to the moon. Most of the rest believe NASA is hiding aliens or controlling the weather or some such nonsense.
Do you have evidence to the contrary you could share?

Many people have also written quite a lot about how the race to the moon was primarily funded because it was a military domination competition. Once the USSR decisively lost, the US stopped doing that expensive science. A good overview of the geopolitics of space exploration and research is the book Dark Skies by Daniel Deudney [2].

Meanwhile the miracle that was the asteroid hunter probe got an easily-overlooked station with an actual sample it brought back from Bennu in an inadequate magnifying display case.
But two days later she'll mention to either me or another space nut like me "Hey, what was that surprise that NASA found on Mars?". And the conversation that sparks will be engaging and interesting for her.
Getting public engagement is a part of how they defend (and increase) their budget, so it makes sense that they would be more likely to use click-baity headlines. ¯\_(ツ)_/¯
