Costco maybe?

Pine64. ("Successful" doesn't have to mean "a megacorp".)

Just starting with "Not totally abhorrent and aiding the destruction of democracy in the US" would be fine.

Instead of working for Zuck or Google or Larry, you can work for Garmin, Shopify, Visa and Mastercard, most banks (they are soulless but some aren't always evil), grocery chains, pretty much any local business, car companies, non-weapon or surveillance based government work, IDEXX, hell even Apple imo and I dislike Apple, nearly every business that isn't "Tech"

Basically just stop pretending that the industry is only Google, Facebook, AWS, Microsoft, and Oracle. There's something like millions of jobs that aren't in those companies.
