One site I went to lowercased my password before storing it unencrypted in the DB, which I only discovered after failing to log in and asking for a password reset mail, so it helpfully emailed me my clear text lowercased password.
Eventually I convinced leadership to invest in basic security after conservative but still embarrassingly high 6-to-7-figure estimates of annual loss expectancy that only took a measly 5 figures a year to eliminate 75% of the risk, but the company only went around to it a long while after I left the place.
I don't know what makes a manager turn off snooze on open PRs for fixing blatant holes.
But if you've got that skill, it can take you far!
