It blows my mind that nowadays, some random tools on internet tells you to do "curl -fsSL https://.... | bash" to install some "binary" things and a lot of people will do it without hesitation. It probably explains why there is so many data leaks recently but it is like we did a 20 years jump back in time in terms of security in just a few years.
I get the hesitation :D But the code is open and the install.sh is as minimal as it gets tbh. Still, as said, I get the hesitation. What a time to be alive. It does not install binaries, it builds the binary by checking out the project basically. You can also do the process manually and use the tool.
I bet 99.9999% of users do not review the code nor the install script.
