I rather try to educate the people I know about the consequences of relying on companies like Meta for things like that hoping it doesn't happen to them. That's all we can do. And I guess contributing to the technology that enables alternatives.
But saying build it yourself isnt educating. It's akin to saying, "You should have known better". Sure. They should have. They probably did. But when someone is asking for help and you say you should have made a different decision 10 years ago to prevent this you are not educating.
There are plenty of alternatives out there to build a community, sell things, etc. The bit about contributing was aimed at people like us who work in software.
