The main downside of any license that is restrictive is that it creates legal boundaries where no technical limitations exist, which on top of preventing the kinds of things you don’t want, can very well prevent totally desirable things as well (prime example is GPL compatibility with ZFS and Linux.) I am not really too concerned personally but suggesting a restrictive license has no downsides or there is not a valid viewpoint where a restrictive license is a negative doesn’t make sense, it’s just not true.
