With all the serious stuff we've requested like mirrors that assault me and my passengers, Tesla releases a new feature to play fart noises? Someone needs to have their priorities reset. No, not all Tesla owners are eleven.
The fart app is definitely silly, and I don't expect to use it. It does seem to be well executed, however, and clearly there are folks who enjoy that sort of thing.
In the mean time, Tesla made some big helpful changes that get lost in the fart discussion. The new firmware, when attached to the new phone app, now gives real time status on the four closest superchargers on you phone and list the four closest destination chargers as well. navigation to one is a single click away - click on it in the phone and it'll load into the car's navigation, even if you aren't in the car at the time.
PIN to drive just got more secure - it shows up in different places on the screen, so they can't narrow the number down by looking at fingerprints.
I was also told by release notes that heated seats will be individually settable as part of preheating from the phone, but I don't appear to have that yet (another phone app update needed?)
So yes, the fart thing is silly - but they haven't stopped making real improvements. And as another poster noted, the fart thing may well be about winning mindshare - getting the name out there to sell cars (Tesla/Elon doesn't believe in advertising, but you better believe they have clever marketing plans...)
