Totally agree! I'm not 100% opposed to your idea, I'm just not a good sales person so if I tried to convince people on Facebook to move away from that platform, I would most likely end up being seen as a conspiracy theorist or something like that.
Before I left facebook I did post a comment in my feed where I announced I'd be leaving Facebook within a certain time frame and that people could find me this and that place, at this or that email and on the phone if they had my number. Wrote a bit about why I had had enough of Facebook, didn't make it political, but focused instead on how Facebook no longer felt like a place where I could interact with family and friends, but more like an advertisement platform where I may be lucky to see one or two posts from people I care about inbetween an endless scroll of ads and brainrot content.
My biggest surprise was how quick some of my friends were to reach out to keep in contact and some were eager to move to Signal so we could still talk conveniently in the future (lets face it, text isnt always the most convenient communication form lol). That was a surprise because I literally thought no one would care that I left.
I will do my best to share things like Signal and the European alternatives with people I care about irl and leave the online convincing to the pros xD I could probably spread the word about feddit on reddit since I haven't deleted my profile yet, just the app. I feel like reddit would be more open to this since more people on there are invested in online communities unlike most people on Meta who just use those platforms to connect with people they know irl already.
I have always thought you could make that point with something like a knife. It is a tool made to assist in chores. You can use the knife to feed your family or kill your family. The knife is just a knife.
But a gun is specifically designed to kill. There is literally no other purpose for the gun. You can't use it in a kitchen. You can't use it to carve tools. Its only use it to take life.
That's why the guns don't kill people mantra rings endlessly hollow to me.
