The same way people migrated from Twitter to... mastodon to ultimately settle on bluesky or go back to twitter.
This reaction is very rushed and I don't think it's going to be very lasting, I'd expect people to go to reels/shorts until maybe another (western, american probably but could be european) alternative appears.
These people are up for grabs, they're not going to stay in Xiaohongshu.
I think the stickiness of the FYP algorithm is not to be underestimated. Xiaohongshu's FYP algorithm is at least as good as TikTok's, and American social media companies (until now) have shown that they either cannot replicate an FYP algorithm of this quality or refuse to for business reasons.
It's very hard to go back to an app with a poor FYP algorithm (ie. Reels, Shorts) after using an app with a good FYP algorithm, and this, along with a knee-jerk reaction against Meta for its perceived role in lobbying for the "TikTok ban" will make capturing ex-TikTok users an uphill struggle for Meta's products.
