These aren't coming from tabloids. They're coming from so-called serious news sources of various types.
The line between tabloids and serious newspapers isn't always clear, as tabloids also do more serious stuff occassionally and the serious papers also do stuff like this sometimes.
Nonetheless, the reasoning is the same: every news source wants as many clicks/reads as possible, so all of them write about things people want to read (in varying degrees, of course). Sensationalism and clickbait will never not be effective.
