I’d suggest learning what libcurl is used for before throwing it out with the bath water ¯\_(ツ)_/¯

It's used for downloading files (and occasionally uploading them) over HTTP(S). It has plenty of other features but that's what it's used for 99% of the time.

What do you think it is used for?

Almost every new car uses libcurl. You can find curl in TVs, gaming consoles, smart watches, smart phones and so on.

Right... and they use it for downloading files over HTTP(S).

Also smart phones, smart watches and TVs generally don't use libcurl for that. Android, iOS and WebOS have their own HTTP stacks. I don't know about cars or consoles.

You seem fixated on "downloading files over HTTP(S)" and are missing the point.

Nearly every videogame for instance use libcurl as their HTTP stack. You know why? Because it's the best HTTP library for C/C++.

If you have a C/C++ application doing HTTP traffic it's likely using cURL. Or, I dunno, you could look at this page to find out: https://curl.se/docs/companies.html
