Don't know about Smosh but Funhaus is under the RoosterTeeth umbrella which seem have just built up this network of sites and viewership that instantly gives any new site they add quite a lot of exposure. They've got access to channels like letsplay and theknow and usually do content and get exposure there too.
Obviously it helps that the Funhaus cast is really charismatic and funny. They've admitted themself that they often try to cater to teens, but from what I've watched of them they're actually a really intelligent and funny bunch who put a lot of work and effort into editing their content and videos to make them entertaining to watch.
The "...while anything even remotely intelligent has to claw for oxygen." part seems also a rather narrow-minded view of things.
Everytime Funhaus comes back up into EZA chat due to the crossover like Elyse turning up or Omar on the past two Easy Updates, I give a customary click to see what the first block of thumbnails over there is:
Then I nope right out of there and feel weird thats the job thats keeping these GT alumni paid up and with seemingly more of a structurally sound future than their old life. I'd struggle to see them being 'proud' of the content they get involved with over there without mental gymnastics and reprogramming going on.
To see things go from GTTV being on broadcast TV with incredibly professional shows to not something worth pursuing while people screaming "rape" into a microphone is where all the money is nowadays is just one of those deep sigh things. I'm an impatient person to the core, so I'm always waiting for the great media cycle to turn and for tastes to flip on their head again.
I guess it just goes to show how important putting our money where our mouths is with showing the Easy Allies they were right to come back and carve out their niche all over again. Just sad its niche is all. I live in hope for the day EZA closes in on 100k Youtube subs, 200k, 300k and so on.
