It’s just not big enough in the EU. Everyone uses WhatsApp. If Google wants to push a regulator to do this then they need to find one in a market where iMessage is actually used.
I’ll just be happy to have RCS support, I don’t want to have to keep emailing pictures to people on iMessage. I could care less about whether I can play 8 ball with them
In the article, it specifically mentions “Business users” and I can torally agree on that. Not many people use iMessage here in the EU or Switzerland anyway and for business I would say practically zero. I have seen bussiness use Threema, Wire, Telegram, Slack or Google Meet.
And heck, if businesses here have customer live chat with messenger, it’s either WhatsApp or Facebook Messenger.
I personally never had to use iMessage after the rise of WhatsApp - neither privately nor in bussiness.
