> The survey was announced on the curl-users and curl-library mailing lists (with reminders), numerous times on Daniel’s Mastodon (@[email protected]) on LinkedIn and on Daniel’s blog (https://daniel.haxx.se/blog).

It's not hard to imagine how that would miss the 99.x% users who just want to download an HTTP/S resource after reading an instruction on some web page.
