This article from Medium provides in-depth coverage of the various reasons why. It goes into all the scientific details of the problems any manned Mars mission would have to face, the psychology of signing up for interplanetary journey to essentially spend the rest of your life on death row, the flimsy and slapdash nature of, and false claims associated with, the Mars One company itself.
But what makes it a particularly good article is that it grounds its narrative in the story of one of the applicants for Mars One, an Australian guy named Josh:

But what makes it a particularly good article is that it grounds its narrative in the story of one of the applicants for Mars One, an Australian guy named Josh:
When Josh was 10 years old, he sat cross-legged on the floor in his parent’s neat, suburban home in Australia, enraptured. It was May 1996 and Andy Thomas had just stepped out of the space shuttle Endeavour and onto the tarmac of Runway 33 of the Kennedy Space Center. In his flight suit, bright orange against the blue of the sky, he talked in his clipped and measured British-sounding tones about seeing his hometown of Adelaide from the God-like vantage of space. These TV images would stick in Josh’s mind like gum to a boot sole.
Andy Thomas was just like Josh, Josh reckoned. He was an Australian. An Australian who’d made it all the way to NASA. Who’d been to space and back. And everyone in the world, it seemed, wanted to talk to him about it. If Andy Thomas had done it, then Josh could do it, too. That could be Josh someday, speaking before the world’s media, beaming out of everyone’s television, one of just over 500 people to ever leave the orbit of this planet. In that moment Josh wanted only one thing out of life: to be an astronaut.
Josh is now 29. He has been a member of the Royal Marine Commandos. An engineer. A physicist. A blast specialist, a mining technician, and, briefly, a scuba instructor. He’s worked for one of the most famous artists alive. He was also a stand-up comedian—he plays Keith the Anger Management Koala, a foul-mouthed, sociopathic character in a furry suit, who provides Josh a remove from himself to exorcise a few of the demons he’s been carrying around. It’s a pretty weird show.
One day in 2012, Josh was sitting in an Edinburgh Starbucks, feeling down, when he came across a call for volunteers for a fledgling space program; the application process would be open soon. There was just one catch. The mission was one way.
To Mars.
This was his shot. This was big. This was it. All these years, fostering that childhood dream. Finally, his life was going to change forever.
When the time came, Josh filled out the form. Could he describe a time when he had been scared? A different time when he had been stressed? Why was it important that the mission be one way?
He paid the registration fee, uploaded a video explaining why he should be chosen for the mission, and hit send.
Then he waited.
