Of course my first reaction was "I hate this" but then I thought about it and whatever I don't care at all. I downloaded the update and it's a new tab. They don't force it on you at all. They very very clearly state that you can opt-out and how to do it. This was tastefully done, which is fresh air in the world of social media crapware.
A little while back I felt this way about 'stickers'. It seemed like a completely unnecessary feature I've never used and designed to achieve parity. Last week I spoke to my 20-something sister and learned that it's basically a must-have for her friend group, who sometimes have entire conversations just with stickers shared in her group. Had no idea, but in hindsight realized I'm no longer tuned in enough to know how…
Creating custom sticker packs is also fun, including memes or cute cats.
But of course I don't speak for everyone my age, and it's different for each culture and personality.
