The long fight to make Apple's iMessage compatible with all devices has raged with little to show for it. But Google (de facto leader of the charge) and other mobile operators are now leveraging the European Union's Digital Market Act (DMA), according to the Financial Times. The law, which goes into effect in 2024, requires that "gatekeepers" not favor their own systems or limit third parties from interoperating within them. Gatekeepers are any company that meets specific financial and usage qualifications, including Google's parent company Alphabet, Apple, Samsung and others.
People with iPhones don't use iMessage either. They use WhatsApp, Telegram, Signal etc.
WhatsApp is not a thing at all in Poland mate. It's either SMS/RCS or fucking Messenger which has to be the worst one ๐ญ
Poland has 15.8 million Whatsapp users.
Might be a western/southern Polish thing. I only know my uncles use it to talk to their children in Britain.
