As an American who looks at WeChat and sees a massive, unintuitive jumbled mess, you've explained in this comment how that could possibly be so popular in China! I feel foolish for not having realized that the UX must make perfect sense to everyone who has used WeChat since the days of it being a simple communication app. By that logic, I'm not sure we could say quite yet that Instagram's bundling is a mistake.
WeChat has lots of things hidden behind low impression entrypoints. You can explore them when you want. Its primary features, chat and moments, are dead simple, like WhatsApp. Facebook on the other hand, are mixing lots of stuff into their main feed, making the experience horrible for everyone
It's not easy to say no as a designer but the best companies are the ones most capable of keeping things as focused on primary UX flows as possible.
TikTok figured this out by making it all about scrolling a simple page of high-density videos, the entire screen is full of the content you want. No extra tapping or side scrolling needed.
Reddit is another company that missed the boat on what made their website great during their redesign. Making it feel top-heavy JS-wise and sparser instead of simple high-density information like newspaper site with simple links. For ex: the first article on old.reddit.com is 100px from the top and can fit 10 articles within 1000px, while the new one starts at 400px and lists 3-4 posts by 1000px (HN is 55px and 20+ posts).
