Being the change you want to see doesn't automatically mean the world changes. It just means live with principles regardless of external factors. You don't like Facebook? Then don't use Facebook. It's as simple as that. Others can take it or leave it.
I just see it as people complaining about Facebook while continuing to use Facebook so it must not be a very big deal to them.
2. Lead a movement to switch away from these apps. This has an insanely high overhead, and requires significant organisation of people and a large individual commitment. This would have a significant effect on Facebook.
This is how I view the problem. This is not an example of people being unwilling to act on their ideals. It's a situation where acting on their ideals would cause them a significant burden with no effect, and causing the intended change would require ridiculously large effort.
This is irrelevant to me and can be left out. My goal is not to hurt Facebook but to not betray my principles.
It’s hard though, because what alternative do people have?
I didn’t log in to my Facebook account for 7 years, and I got way out of touch with most of my old friends in different cities.
Sure, occasionally people get frustrated that you are not on these platforms, however I ended up being lot more responsive and attentive to non social media forms of communication. Social media is usually low effort, I rather have one person wishing me with personal email on my birthday, rather than hundreds of meaningless FB posts.
It was actually harder for business contacts than personal, customers want to chat in whatever works for them, harder to say no to someone paying you. However Teams/Slack has helped a lot and dose of compliance reasons which customers find easier to go along with.
