This is sort of like why plumbers hate chemical drain cleaners: you call the plumber only on the times that it doesn't work, and then pay them handsomely to clean up your mess. For all the times that Drano works, you never call the plumber in the first place, and so they never see it. Likewise, you only hire a SRE if a.) you have the budget to hire at all, which the vast majority of startups do not and b.) reliability is shitty enough that you need to hire someone to fix it. All the Django setups that hum along fine do not need SREs; the founders continue to rake in the money and don't need to hire anyone.
