Don't do that. If there are no free and legal download on the web, then we can't >use publicly redistributed application without the developer's explicit consent.
No, this software is free. Developer don't have enough money to create site for client of his minecraft hosting. He put an application on CollyNodes discord server(because hosting haven't got site) with access for every member.
I can't find CollyNodes on the web. The only search results are from an obscure russian website. Doesn't looks like an official minecraft application to me.
It's normal, because it's not an official minecraft server launcher(there is no official Minecraft server launcher). This app used as client, that connecting to nodes and launching server from there, instead of site that should to the same.
