You not being a fan of something doesn’t make it crap. I’d take iMessage and Signal over WhatsApp and its Meta AI mess any day.iMessage and the blue bubbles crap is a US centric thing.
In the end, WhatsApp is still owned by Zuckerberg, and the amount of data collection from the app is staggering regardless of E2EE. So much so that I even have contact access disabled due to an incident in the past.
It’s not the IP address that you need to be worried about these days, but the trackers across the apps. NordVPN blocks some trackers but not as much as a full-fledged one like NextDNS. The biggest benefit you get from using a VPN is obscuring your location, but tracking is much more than pins on a map.I've been using NordVPN for years to block ads so that will be one of the apps I download first.
Use a VPN when on public, unsecured networks, but block trackers everywhere and always if you’re concerned with privacy.
