People are talking about a TV show and it sounds interesting.
You look up the streaming service. Damn, you aren't subscribed to this service. None of the ones you are already subscribed to has the show, but you really want to watch it.
So you subscribe to a new service, provide your email address and your payment information.
Sounds easy. Millions of people do this every day.
But yet, people complain about the #Mastodon onboarding.
