Aside from the fact that because they work for Sky, they're probably literally being instructed by producers to generate fake conflict, they're just like anyone else who lives by the attention grift.
They come in with their own genuine opinions. As they deliver them publicly, they get a massive amount of engagement (good or bad) for the highly contentious or reassuring opinions, while other things they say simply disappear.
When they get all that attention, they get a big helping of dopamine and some handler or agent probably compliments them for being "hard-hitting" or "topical", or maybe some calls them a "dickhead" on Twitter, or they get "cancelled"—the greatest badge of honour of all.
Naturally they keep hitting the highly contentious or reassuring opinions that deliver that engagement, again and again. Pretty soon, it turns out most of them don't have their own genuine opinions any more.
It's at this stage of the process you get Gary Neville, who though he has a soul the size of a pebble, a face like crumpled origami and a spirit as twisted as that of a neglected gimp, appears to have the intelligence at least of some kind of rat-dog or perhaps a working dachshund, being recorded and uploaded to YouTube as he declares that Manchester United's going to come second this season.
