And why not? cURL was not developed for PHP, but why not use it if
it's available?

Using fsockopen() is not that simple compared to cURL; you have to keep
track of redirects, cookies, etc., and remember to separate HTTP
headers from the data proper. As to file()/readfile(), PHP sometimes
experiences problems opening dynamically generated remote files via
file system functions, even with allow_url_fopen = On. Sometimes it
even generates error messages like these:
Warning: file([URL]) - Success in file.php on line X
Warning: fopen([URL], 'r') - Undefined error: 0
