One exception is CD Project Red.U can buy cyberpunk through their store on gog.com and u will exactly owning it since u will able to download executable installer and game will have no DRM.Pay once own forever,same for witcher 3 and other games which they distribute on gog.com

Yesterday played in it.Pirated one version works fine since it’s doesn’t relay on any laucher ;)

I am using both for enough long time,mutlidevice synchronization it’s nightmare in xmpp,also usual xmpp isplaintext.So when u wanna use encryptions like omemo so far not always guaranteed that ur encryption key will be delivered to ur new device which u connected.Also u cannot control sessions.So if u would be hacked u would not be notified,and u don’t have ability to kick out this dude session.But yes xmpp more light about resources and works faster for now.
