When you download the Netflix app, you only get a sign in button. The only extra info you get about how to get a Netflix account is a help button that calls support. I don’t know what Hulu does, but I presume something similar.
That's a good point. Most of this boils down to not having an upgrade nag prompt. Since netflix doesn't have a free tier, they are less affected. Spotify is in a tough spot because they want free users to upgrade.
