Try not using Wechat in China. Facebook's Whatsapp is going in that direction in the Netherlands and probably other European countries: I don't yet need it for daily life, but a lot of services are moving to supporting WhatsApp and turning off things like regular phone support, website chat, etc. The only things where it was a requirement so far, were things I didn't yet care about (like sending in voice messages to be used in a podcast, or being part of the neighborhood gossip and tool-sharing community chat) but I bet it won't stay that way forever and sooner or later a company will discontinue email support in favor of "just message us on Whatsapp". Between going back to the 80s and writing/printing letters and sending them in the mail, and installing WhatsApp, any reasonable person will begrudgingly click that agree button no matter if they really agree. I'd say they were extorted at that point and it is not voluntarily/freely given consent, even if they technically have made that choice themselves

Tell that to the embedded Facebook trackers ubiquitous throughout the web

One of they key points of DNA is exactly that you likely can not avoid these services.

Keeo in mind, it is only the largest 7 tech companies in the world that has to comply.

It is incredibly few companies.

it's okay, your acquaintances will share their contact loss lists and so you can't miss out
