I can't understand how Apple keeps getting away scot-free, considering this type of scrutiny exists and how their services work.
Their services are an afterthought in terms of market share, particularly in Europe. For example no-one really gives a shit about iMessage and “green bubbles” here because most folks are just using WhatsApp.
And which EU countries are those? I know a few in the 60s% market share range but that would hardly be considered “very high”.
