Do you have specifics on size of equity grants and timings and levels? There are lots of recent counter-examples; I have a relative who joined Uber shortly before IPO, he didn't get much. The pre-IPO valuation was already high and there were enough employees that grant sizes were not large. Even joining Zoom/Snowflake/Mongo seems like you would've had to time it very well to make sure you got in before the peak and vested in time to sell before the fall. Some other googling of recent tech IPOs shows a lot of drops: HashiCorp, Confluent, Monday.com, Squarespace... do you retire if you join companies like that just before IPO a few times in a row?
