Why does Bitbucket still use SHA1 for SSH?

[kaushalyap]

In Fedora 33 SHA1 was removed. I tried to clone Bitbucket repo using SSH and failed. Found the solution here.

But I am wondering why BB still use SHA1 for SSH? Github works fine without changes in the ~/.ssh/config. Is not using SHA1 less secure?

ssh -T git@bitbucket.org
git@bitbucket.org: Permission denied (publickey).

the only solution was above link  thank @kaushalyap

Cheers
