Don't use it. Refuse to talk with anyone that says they want me to use it. It's been working great.
Had to install and use an anonymous number that no one has for like 2 things that I was really in need to for interacting with some businesses though and for when many people were laid off in the company and that's where I needed to find some info.
Either I use Signal only or SMS which has worked great for many years. Now with RCS it's the same as any other internet based chat even with video calls.
Either all or nothing. But for certain not contributing to the destruction of humanity by using Meta products.
