That's cynical. If someone spent their time making quality things people enjoy, they can charge whatever currency they'd like. If that currency is an email address so that you can be contacted later in hopes of selling you paid products or earning through referrals, then that's their prerogative. It doesn't make them a _lying piece of crap_.

If you use a catchall, create an address for that service. It it does something you don't like, cancel later.
