Last I checked (about a year ago I think) Whatsapp backups were platform-locked as well.

I'm not sure why you are being downvoted. Whatsapp backups are still platform locked to this day. But that may change soon.

Not completely. WhatsApp pushed out an Android-compatible backup option on their BlackBerry 10 app when they announced that they were shutting the app down a few years ago. But it was behind a notice that said it was 'not supported', even though it worked fine. Only to Android though.

You can get a dump of all your messages with someone pretty easily.

I transferred between two Android phones, and had to re-pair desktop clients. It all worked, but now the desktop client won't receive messages I've sent via phone.

Also video calls still don't synchronize orientation. It's very hard not to stoop down to use more vulgar language to express my feelings about this.

This is insanely annoying in real life.

Whatsapp does, so it's probably not that critical of a feature.

Most people don't switch platforms very often so it's not a big deal to them and just a corner case. Also most people don't care that much about old messages so again a corner case.
