Remove the Skype/Lync setting from Zoom AND the link from meetings. Skype was discontinued in 2021

Microsoft completely discontinued Skype in 2021. It no longer exists.
However Zoom still has a setting in the ADMIN settings (that only the Admin for a company can change) to enable the link to appear.
Just remove the option already and by default remove the link from appearing for meetings.
There's literally NO reason for the link to exist and it makes Zoom look old, outdated and unprofessional and it makes Zoom users look old, outdated and unprofessional to have a link to a product that doesn't even exist anymore.
Might as well link to Netscape Navigator.
