Most of the people using it probably don't even know what SSH is, let alone using a VPS to maintain a personal bot for them for years with no maintenance. They know Vercel and Supabase. They will run it on their local machine and just keep clicking yes to everything until they get the result they want.
That is not how the software works.. I take it you have no first hand knowledge with this stack? This isn't a double click the exe and you are off the races. The hostinger vps is actually the easiest way for a normie to get this running.
This is not true. It is useful without having access to a single account of mine. My setup runs on its own accounts and hardware. Obviously it is not sending out emails from my inbox, but that is not a usecase of any value to me. And if it was, there are actually plenty of ways to do that safely as well.
If you think you need to give it the keys to your kingdoom to be useful, you are not actually experimenting with this stack but regurgitating the words of others. I really don't understand the mindset of comments like this.
