I mean, not really. I've been around since the Something Awful forum days so I'm pretty familiar with the whole deal and Lewis in general. TL;DR at the end.
He started with a very funny friend (Simon) and made a ton of World of Warcraft videos on Youtube featuring said funny friend. As it gained in popularity more of their Something Awful/Ye Olde Goone Squade friends started joining in...which is pretty much when it became the Yogscast.
After finding middling success with these WoW vids and the YoGPod for a while he started up a Minecraft series that blew up in popularity alongside the game itself and Lewis started outsourcing various bits of production to friends and acquaintances because he couldn't handle it himself. I actually became involved during the Shadows of Israphel days, but in the interests of not completely doxing myself I'll just say I had a minor role but still bore witness to a lot of the behind the scenes stuff at the time.
Alongside this series was born the Yogscast forums which Lewis handed off to folks like Peva, phatima and (pirate)Tinman to run. Tinman, as some of you might know, ended up embezzling tens of thousands of pounds via ads on the site and took off. Lewis couldn't bring himself to deal with it, because Lewis, so he brought in someone from the outside, ridgedog, to be a hatchet man. Ridge then basically fired off a bunch of good folks and alienated half the community which ended up being the end of the Yogscast forum because Lewis at some point couldn't be arsed with it anymore and dropped the whole thing rather than work at fixing it. Ridgedog was fired a year or so after Lewis hired him to do his dirty work. Other folks eventually stepped into leadership roles and got the ball rolling again at YogTowers.
Then along comes the whole Sjin/Turps/Caff (and "others", though those weren't as public) thing and again it comes down to Lewis not wanting to deal with anything problematic. He brushed aside allegations and basically ignored it for the most part until it became too big to ignore. It wasn't until Yogscast as a whole was basically under threat of collapse from all of these shitty people doing shitty things that he finally decided to get off his ass--because he was practically forced to at that point.
I stopped associating/working with Yogscast around this time precisely because of how Lewis (and other top-level folks, but primarily Lewis) wasn't dealing with it, so my firsthand knowledge ends around here. I say working with and not for because I was never paid for the minor projects I did for them and Lewis never bothered communicating with me directly past giving me a task and then ignoring followup questions or concerns I had.
At any rate, since then Lewis has pretty much been the guy who calls other businesses/charities/organizations to ask about participation in Jingle Jam or sponsorships since he's the face of the company, while the majority of the rest of the work gets done by more competent folks with social skills.
The TL;DR of it is that Lewis is an awkward nerd who stumbled into success by exploiting his funnier friends (I don't mean exploiting altogether negatively here) but whenever things get hard he either throws his hands up in resignation or retreats and tasks other people to deal with it instead of getting his hands dirty.
Oh, and then there's the whole "Lewis is being a creep on dating apps around Bristol" thing that came out a few years ago but I have no knowledge of that past what's been posted on Reddit so all I can say about that is it's believable given he rarely knows how to act appropriately in social settings. I'll chalk that one up to something he can't help, though.
