The shittiness of a place is defined by a lot more, and more important, attributes than alert hygiene. Culture, pay, location, industry, leadership. If one leaves companies for (relatively) minor things like that, there are basically no companies left to work for.
Alert hygiene is a symptom of bad culture. Not the only one of course.
Or, it can be self-evident to all that today's work can deliver more benefit if focused elsewhere, instead of root-causing fickle alert flakes. Customers buy products and services, not alert hygiene.
