I use bxactions (not FOSS) to use it as a play/pause button. Can easily pause and skip tracks keeping the phone in my pocket.

A lot of them have already said they’d withdraw (facetime, iMessage, signal, WhatsApp included).

I’ve heard that too, product launches = promotion so they keep churning them out.
