I have been riding fat full time for quite awhile. I am very aware of tire pressure as well as the gambit of fat issues, I.E., tires, tubes, tubeless, rim width, tire width, tire TPI, Knight Rider, bump steer, self steer, massage steer, air temp, trail conditions, snow type, ice type, sand type, body type, she's/he's not my type.
I also know how to set up suspension after riding primarily gravity (WTF does that mean industry, don't all bikes use gravity?) bikes for a solid amount of years and adjusting my suspension for courses/weather/conditions enter other here .
That being said, it wasn't and isn't for me. But it is OKAY if it is for you, no one on here will judge.
I wanted it to be for me, I really wanted the Bucksaw to be for me, but neither were. When I build another fatty, it too will be ridged. 5" tires give me enough squish. IMO, the biggest and best upgrade are solid wheels with primo tires. In fact, tires probably play one of the largest factors in my fatty experience.
