I used to work for Airbnb. When I left, I lost a few things like admin settings on the repo but they let me maintain it. Not sure what would happen if they didn’t… Nobody there has the time or context to do anything more than a rubber stamp.
Maintainer of Lottie for Android here. Because it’s maintained as a passion project on nights and weekends by a few people. This contribution a rare exception in that it was actually funded and built during work hours at Airbnb. I left Airbnb in 2018 but am still the sole maintainer of the Android library, for example.

Maintainer of Lottie for Android here. I left Airbnb 5 years ago and have maintained the library 100% on nights and weekends for the past 6 years. I know your comment was sarcasm but fyi ;)

Tonal is the world's smartest home gym. It's a single device that mounts to your wall, has a giant screen (powered by Android), and uses an electromagnetic motor to provide up to 200lbs of resistance. It's genuinely one of the most incredible new consumer products on sale today. It works phenomenally well and we're just beginning to tap into the full potential of the hardware.
We're an engineer-founded company so strong engineering is at the roots of everything we do. I'm the engineering manager for the Android team. We work on everything you would touch and interact with on Tonal's screen.
I personally exclusively work out on Tonal and I'm stronger than I have ever been before. It's truly incredible what it's capable of.
We're hiring passionate product-minded Android engineers as well as nearly every other discipline (backend, data science, computer vision, dev ops, media streaming, iOS, Flutter (for our mobile app), and more).

We just raised a $250mm Series E at a $1.6B valuation, grew 8x in 2020, and are on track to see enormous growth in 2021.
We have many open positions across the company. It's an extremely exciting time to join the company.
I am the sole maintainer of airbnb/lottie-android despite the fact that I left the company almost 2 years ago and it is used by tens of thousands of companies including Google, Samsung, Microsoft, Uber, Netflix, and countless others.
We wanted to leverage our existing infra to have a consistent experience between native and RN screens. For example, you want to have the same network cache.
The vast majority of the 100 always have been and are still Android and iOS devs. React Native never made up more than 10-20% of our mobile engineers and many of them came from Android or iOS backgrounds.
Author of Lottie Android here. The bodymovin to avd plugin is extremely beta and only supports a sublet of after effects features and none of the lottie features such as manually setting progress or dynamic properties.
We have definitely not stopped using React Native! Not sure where you got that impression. We continue to heavily invest in it as well as native platforms and make a case by case decision for all new products.
We have actually be using an internal navigation framework that is unfortunately quite tightly coupled to our app. It's been working very week for us which is why we decided to make an open source "clone" of it. Our original intention was to migrate our internal navigation library over to the open source clone we made. However, with the realities of life, we haven't had the time to actually do that yet which is why we haven't been maintaining it.
Like Leland said above, we're still working hard and making exciting progress on React Native but we continue to invest in native platforms as well and product teams make a case by case decision on which one to use.
The performance does definitely depend on the complexity of the animation.
Small icons like the hamburger menu, wish list heart, hamburger arrow, etc run at 60fps. Even the main Lottie logo (http://airbnb.design/lottie/) that has pretty complex trim paths renders at ~60fps.
Masks and mattes are the feature that incur the largest performance hit because they require allocating a bitmap (8 bit for mattes and 32 bit for masks), rendering to them, then drawing them back to the canvas.
