It depends -- with a community build script, you're relying on (and trusting!) a third party to maintain it and not do anything malicious. Much easier to pay a few bucks for first party binaries. At least in my eyes.

This is how every distro repo works and likely where you would get that binary from.

In Windows, people willingly download shady binary from piracy sites all the time to avoid paying for software.

I think you underestimate the incentive of free (beer) stuffs.
