If you were going to commit suicide it’s a weird way of doing it, essentially by dehydration, by someone who would understand exactly how rough that would be. I guess if the intention was to commit suicide but not have his body found…making himself look lost by accident…that would explain it. Some digging around on his mental state such his internet history if deleted may be retrieved if British consulate have any suspicion of that. If he’s been researching dehydration or how to hide from mountain rescue. Or if he’s been prescribed any medications he could have stockpiled for an overdose, or been researching videos of that particular mountain.
I think they are clutching at straws now with this Abyss cave search. To get there he had to to reach the next marina and instead of going into the building to ask for help, water or shade, he has got in the sea without leaving trace behind of the backpack, clothes, umbrella, not seen on the building’s cctv or by the people there, and swam into a cave he wouldn’t know is safe or anything about the currents. While knowing that he had a history of transient anemia caused by a sudden change in temperate that happened in water. It’s much more likely he’s seen the signpost for Symi town part way through the route and turned onto that even more dangerous path, that it sounds like the rescue team aren’t even confident at searching properly it’s so unsafe even for them.
They will likely have different crews doing land and water searches so if the water crew have done the obvious places already they may just be being thorough rather than having any real reason to think he would have swam into a cave.

Re the media coverage, it’s the same reason only particular celebrities are constantly in the newspapers, they can use the website data to see what/who is best clickbait and then they build on that. The British public as a whole may have more affection and concern for Dr Mosley, but may be more likely to click on an article about the Kardashians. It’s just pure trend following and algorithms, if the articles are getting enough clicks they stay front page for longer. You’ve also got the sideline stuff. The Philip Scofield scandal was a great example of a story that was a wild success for clickbait on its own, but then got amplified into a mega media storm by all the celebrity and tv boss reactions to it being scrutinised day after day and something in the scheme of everything going on in the world was a tiny story ended up dominating headlines for 3 weeks. With this Dr Mosley story there isn’t much commentary on the disappearance itself coming out each day, even though it’s a mystery and it’s been developing, it’s not that complicated to understand that he took a strange and dangerous decision and became difficult to find in that terrain.
the mystery isn’t really what has happened to him, but if he knew he was walking into danger or not and the whys and wherefores of that decision. The only real mystery is his mental and medical state when he chose to take that path instead of waiting for a bus or sitting in a cafe.
