This is probably specific to the Pixel phones, not sure how much if any is relevant to other manufacturers.

Call screening and spam filtering is amazing. Having the phone automatically screen unknown callers means I haven't had to deal with a spam caller in years. And valid callers don't seem to have any problems understanding whats happening anymore. I used to get several who confused it for a voice mail when it first came out, but now it seems they understand how to leave a screening message and wait for me to pick up.

The phone tree and hold for me when calling businesses. Being able to read the options and click the text makes it so much easier to get through the options without having to really pay attention, then having it hold for me until a person answers lets me do other things instead of having to keep listening.

Song identification on the lock screen. Whether I'm out at a bar or restaurant or at home watching a TV show and a song I like but don't know starts playing, being able to see exactly what it is without even touching my phone is so convenient. I've found so many cool new bands I never would have without this feature. Its also amazing how it can often identify covers made specifically for TV shows right when they first air.

Amazing camera and cool features like photo sphere and the new magic eraser. The camera might not be as head and shoulders above Samsung and Apple as it was in the past but it's still always amazing how well it does in different conditions.
Free speech means that the government can't silence citizens outside of specific protections. It doesn't mean that private companies are required to give you a microphone. I highly doubt Spotify will take Rogan off the air anytime soon considering how much money he makes them, but if they did it wouldn't be restricting his free speech in any way as there are a magnitude of other places he can talk, from other online platforms to a soapbox on the corner of 5th Ave.
