For me it's like "oh, I didn't know Wallet was an advertising app", I thought it was something I paid for with the purchase of my phone. But I was wrong. It's just adware. "We'll store your boarding pass if you'll let us spam you about movie tickets." Do not want. I disabled notifications. Now a year from now, I'll be searching for some pass in my wallet. Someone will say "don't you get a notification when you get to the venue"? I'll be like "no I've never seen that work". Multiply that by everyone, and suddenly the buzz is "Apple Wallet doesn't work. Trust my money and credit cards with something that doesn't work? No thank you." And now people are buying a Garmin watch for Garmin Pay instead of an Apple Watch for Apple Pay.
Really dumb. Huge mistake. It makes me sad that they don't care about their own brand. "We won the smartphone wars, let's cash in!" Winning is temporary, but losing is forever.
