Before 2020, ZeroSSL used to be a browser-based acme client using Lets Encrypt. I don't doubt that money was involved, and they switched to Comodo (now Sectigo), with no notice that I could think of. I used them for a few one-off certificates, but this rug-pull caught me off guard. I'd happily watch if they go down in this dumpster fire.
