This is some very SV-centric view. That kind of transparency is possible with up to ~50 employees and plenty of businesses in the 10-50 person range are stable enough you can assume your job is safe. Not everywhere is searching for PMF-to-hyperscale.

My first real job was at a company in Pennsylvania with a few dozen employees. They laid off half their staff and implemented mandatory overtime. Many of my college friends that never left the area lost their jobs during the pandemic working for exactly the kinds of companies you describe. Every five to ten years of my adulthood has been marked with economic downturn that overwhelmingly shutter small businesses. What kind of stability is that?
