Because many of the problems have extended out over years now and several updates with no fix in sight. This is why I used the term "persistent" several times because it's an important word in this conversation. It's not like a bug just surfaced with the latest update and is already being fixed in the upcoming update. (But even if it was a small bug that just presented in the latest update that just means more man hours should have been applied to testing and debugging prior to release rather than making us the test mules.) This is stuff that they can't seem to get right over several updates and yet waste man hours on coding and testing fart apps and video games that do NOTHING to fix the actual problems people are having.
Stop diverting resources to BS when the meat and potatoes of what you're selling requires attention Tesla!
I think the easter eggs started as a lark (probably Elon's idea given his goofy personality), but then they realized it was generating tons of free marketing for them, so they kept doing it (and now with a business case behind it).
Overall, I think Tesla's approach to software development is very cynical and reminiscent of VW's "perceived quality" campaign they began about 15 years go. VW realized that if they used nicer plastics/materials in places that customers would notice in the showroom (along with having tight panel gaps), customers would assume the rest of the car was high quality thus allowing them to skimp on parts that you can't see.
Tesla's infotainment system makes for a great demo in the showroom. You're dazzled by the size, speed and crisp graphics. Ha- wow - it even has a "fart app" and video games! If it has that it must be able to do everything! Only when you start digging in and actually using it do all the underlying problems (bugs, missing features, and usability issues) become noticeable. When I test drove a Model 3 several months ago, I happened to ask about several audio/phone integration features that I'm used to on my BMW. The sales guy said "yeah...this (gesturing to the screen) isn't really tesla's strength". Which, of course, is very true but runs counter to the narrative that they've created for themselves and sold to the general public.
On a very cynical level, this approach makes sense for them as Elon has decided to prioritize growth above everything. So, with limited resources, he invests in the "sizzle" necessary to sell cars to new customers. I don't know how that plays out when/if the company survives long enough that it needs to court repeat buyers. But, for now, it's clear they're going all out on a growth above all else strategy.
Keeping Wall Street happy aside, I wonder if this approach makes sense given that they have achieved/or are close to achieving sufficient volume for profitability. Only if Elon's wildest dreams come true, and they manage to flip the switch to enable Model 3s to become a fleet of robotaxis, does it begin to make sense. He's just optimistic and crazy enough to believe that so maybe that's his reasoning behind pushing for so much growth.
