Probably, though the founder of CSS-Tricks probably did when he sold it. But many on this site are SWE and they maybe didn't make a million in the past two years, but in the past 5 years, the number will be significant.
I assume DO didn't have 11% technical writers. These numbers are hard to judge if you don't know who got laid off.
Their tech writers were under their marketing team, and the CMO got exited as part of this. At least one tech writing team got laid off.[1] Their opt-in list includes six technical writers or editors out of about 152, but I've seen more writers announce on LinkedIn than are listed here. (Engineering took it on the chin, 73 listed.)[2]
DO had invested a lot over the last few years into expanding its technical content library as a SEO strategy. They seem to have completely backed out of that investment.
Coyier's $4M exit was nice, sure. Built on 15 years of work, though, alongside his primary job being a developer/designer and CodePen founder who also wrote, not as a full-time writer.
Still standing by my guarantee that no technical writer here got north of $1M of salary or compensation for two years of work. Not even close. If any got north of $500k they're both role models and were probably overpaid for the market.
