It's time for Microsoft to have another XPSP2 moment. No more AI, no more features. Just fixes. When I was working on Windows XP, Blaster hit. It was a big enough deal that we set aside all feature work. For the next several months, all we did was improve security. We

It's difficult for me to express in words just how frustrating it is when Microsoft, Google, AND Apple try (constantly) to force me to save online (onto THEIR cloud) instead of locally, removing my options. I literally HATE it. Stop taking away my choices. Like if you agree.

"If your spouse won't use 24/7 location tracking, they must be shady." “If your kid doesn’t want your spyware on their phone, they must be up to no good.” “If you don’t want govt backdoors, you must be hiding something.” This is how privacy gets demonized. We must resist it.

I wouldn’t say that Will and I are battling but I do disagree. Because there are big differences between Signal and WhatsApp. Signal is the gold standard in private comms. We’re open source, nonprofit, and we develop and apply e2ee and privacy preserving tech across our system
Meredith Whittaker, president of Signal, disagrees with Will Cathcart's claim of little difference between WhatsApp and Signal. #Signal #WhatsApp #app #marketing
