Not owning an iPhone, I don't have a horse in the race, but if company X is going to make a client for their service, and for whatever reason you need to use their client, if they are not allowed to use Electron, then they will use a different toolkit. If you don't like Electron apps, then this is a win for you personally. Too many services can only be accessed with the official app, which means it's not like you can just download the "not made with electron" version.
