Nothing stops them from doing so, but major browsers and possibly other programs won't trust such certificates. https://en.wikipedia.org/wiki/Certificate_Transparency#Manda...

That depends on location and GitHub pages generally take a while to execute all the javascript for a usable page even after the html is fetched while pages on Codeberg require much less javascript to be usable and are quite usable even without javascript.

Here are my results for what it's worth

  $ time curl -o /dev/null -s -L 'https://codeberg.org'

  real    0m0.907s
  user    0m0.027s
  sys     0m0.009s

  $ time curl -o /dev/null -s -L 'https://github.com/'

  real    0m0.514s
  user    0m0.028s
  sys     0m0.016s
