Policehave used the "very legitimate grievance" the public has with large tech companies like Metaabout data collection and surveillance as a pretext to undermine user privacy.

The first step in protecting our privacy from snooping dis-services is to reject nonfree(non-libre) clients and apps. Nearly all apps are nonfree, and most organizations' web sitesrun nonfree software in the users' browser. Once they send private data to the server, there ishardly any limit in practice to where it will go. (There are some dis-services that explicitdemand users enter sensitive private data — those pose various more complex problems.)

I've considered using Signal, since the client program (what I would need to run) is freesoftware. However, it requires having a portable phone, and thatrequirement conclusively excludes me.
