I hope you're fine with Telegram sharing your location data.
Not turning that on is pretty easy.
It's still sharing data. Sorry.
source? I assume you are refer to the thing that went around yesterday? Then no, there is a big difference between the option to share data to get a feature (even though I'd agree the feature isn't well-designed) and what WhatsApp is doing here.
What percentage of those messages are end-to-end encrypted?
Only secret chats, and seems people using WhatsApp, tiktok or FB do not care
Zero, but I guess we're not particularly worried about it?
