My boss at the time (I was a writer for a tech magazine) asked me to review FreeBSD. I couldn’t get it to install (at all) so someone suggested Linux (Slackware) which was an insane idea at the time around 1995 or 1996. Slackware sort of worked, no sound and I had to do various really annoying things to get it to see my modem (which never really worked). But something about it was interesting and I stuck with it.
I worked for a company we had 300 websites, the boss wanted to buy certs. I told him about Lets Encrypt. He loved the idea it saved us a bunch of money. I suggest we donate $100 to them. Hes says “NO F-ing way!”.
