Actually police (and governments) don’t need to purchase your data. They can gather anything and everything from what people share publicly and constantly on social media. Countless numbers of people have been arrested because of what they shared publicly and the metadata included with that share.
If they need criminal info they have immediate access to it.
The concern isn’t that you do something wrong, it’s that the data that you put out there can be used against you in countless ways. Marketing, sales, and so on are the least of your worries. If anyone wants to threaten you, your loved one’s, or even trick you into thinking they are in a threat situation, most people don’t realize how easy that could be with the data they give away daily.
Just and FYI those are my pages and Video, and I also don’t have sliding sync working yet. I work on it here and there, but other than Element X, I’ve had no issues getting clients to connect to my servers running dendrite. I’ll update those docs, and probably do an update video when I get it working on Dendrite.
