> Not if they integrate the messaging infrastructures as described in the article...
WhatsApp is a phone app. Even if Facebook heavily integrates the messaging infrastructures, the problem an acquirer has is porting the existing users over to a new messaging infrastructure. Signal-based infrastructure is (relatively) turn key, most of the software is already developed, deployed, and tested. After you have that, the main thing you have to do is push a new version of the app out to all the different app stores that uses your new infrastructure. Bam, you're done.
I am simplifying certain things (there'd definitely be a somewhat complex transition period where your new app would have to support both infrastructures), but my main point is that this integration is not as big of a barrier to re-separation as it may seem.

If you're selling it, it would be your job to port it. This wouldn't be the purchaser's job, it would be Facebook's job. It would be like expecting someone to dismantle a bed your selling on eBay. No one in their right mind would agree to dismantle it for you unless you were giving it away.
