Q. Is this really as harmful as you think?
A. Go to your parents house, your grandparents house etc and look at their Windows PC, look at the installed software in the past year, and try to use the device. Run some antivirus scans. There’s no way this implementation doesn’t end in tears — there’s a reason there’s a trillion dollar security industry, and that most problems revolve around malware and endpoints.
But it doesn’t list them does it? With e.g. zsh I can have the list of flags alongside their explanation, which is not the case with PS I think? I think even bash has it on more recent distros (not entirely sure)
