Thankfully they've now shipped their own product, YouTube Music.
And Google Pay, imagine my surprise back in 2021 when I signed up for Waymo and realized I had to manually type in my credit card. No Google Pay??? C'mon y'all, you're Alphabet!
Next thing you know, they're going to add Alexa support before Assistant/Gemini. The PMs at Alphabet are famously incompetent. Another example from the archives: Google wrote the original official Twitter app for Android instead of letting Twitter do it themselves. It wasn't to help the Android platform because multiple third party Twitter apps for Android already existed.
Its is corporate fiefdom. Everybody trying to one up other executives to show impact instead of working together towards a unified goal. The bigger the company the more we see this phenomena. Nobody gets promotion if you just used existing internal service.
