This is why several years ago, Google made it a requirement for all OEMs playing in their Google ecosystem had to add the boot animation that said "Powered by Android" because it helped build a brand. If you were running a Motorola, HTC, LG, or Samsung device that used Google Play Services, you were going to make it known that you were using Android.

This type of tagline may not matter too much in the distant future, but for now I do see it's value for Nostr.
