The corollary of that line of thought though is that by preventing tech companies from dabbling in microprocessors you reduce competition in the microprocessor space- a sector which has proven very prone to the formation of monopolies/duopolies. If anything, we want to encourage more new competitors in that space, not fewer.

Also, it’d be essentially arbitrary. Is it OK for Apple to design its own microprocessors, but not Amazon- and if so, why? Is Google allowed if it uses them in phones like Apple, but not if it uses them in data centres like Amazon?

What with Trump recently declaring (in his usual completely coherent and not at all deranged manner) that Google Are Bad, the Supreme Court might not necessarily be feeling so keen to help out on this one.

The UK isn’t quite that far, but it’s absolutely the dominant text messaging and calling app in the UK. Nobody uses the built in Android or Apple tools anymore, and I’m as likely to receive a WhatsApp voice call as an actual phone call these days.

I have Signal on my phone, but I’ve literally never had a cause to use it; I’ve simply got no contacts on there.
