It's clickbait because it's not actually news; Ewan was just restating something that was already known. It's like somebody doing a breaking news story to tell the world that water is wet.
For example, an article that says something may be so, which means also that it may not be so, though that goes unsaid. By the law of the excluded middle, it is always, vacuously, and tautologically true. True, but made ya click.
Another classic example of not untrue clickbait is also posing questions in the title like, "Is [name] pregnant?!" and then the article says "Nope". It's not untrue, but it's stil clickbait.
“Mara Jade is Rey’s Mother?!” *spends five monutes scrolling past eight flash ads* No. But despite the character being retconned out of existence and never even being mentioned in the movies, some internet fans are fantasising about it! ~Three Hours Later~ “Jyn is Pregnant with Rey?!”
Someone who works at LucasFilm has confirmed that they were working on a movie that involved Tatooine, though that could mean anything. Not necessarily Obi-Wan.
I can't remember any sites where I saw it, but I do remember seeing that pop up in the news recently.
I think it may have been on the proposed SW stand-alone that centred on Mos Eisley Cantina - essentially a ‘Tales from the Cantina’ type movie - one that was set on Tatooine - but apparently has been scrapped, and was kept under wraps (so much so, that very little info exists about it).
