'StartAllBack.com', a shell replacement software contacts remote Russian servers for updates

Is anyone here familiar with the software ‘StartAllBack’ or ‘StartIsBack’?
It’s a shell replacement for Windows 11. It allows you to bring back the classic start menus, Aero, etc.

It’s contacting several remote servers and IPs in Russia.

Should I be worried?
