I use Slack, WhatsApp, Discord and Facebook's Messenger. On my computers, rather than installing dedicated apps, I've always just used these services' browser versions. It allows me to block ads with my browser's ad blocker and modify the UIs with other extensions that I use.

But in terms of privacy — and more specifically, in terms of what the service has access to outside of their own walled gardens — is there a difference between using these services through a browser or their dedicated apps? I use both Windows and Mac computers, if that makes a difference. My browser of choice is Firefox and I run the services in their own containers.

On my phone, I just use the provided apps and get notifications that way. I am well aware that most of these protocols are not great for privacy to begin with, but I'm not currently looking for other messaging systems.

To be clear, Matrix as in the communication protocol. Curious if anyone has any recommendations for communities there. Personally I am mostly in the NixOS space, since that is the official chat for issues and questions.

Here in the States, you hear about your insurance company waiving co-pays for tele-health therapy visits in these “uncertain times,” but searching for providers confronts you with even more uncertainty. How do you evaluate their practices for safety and privacy? Every other practitioner subscribes to a different platform. Some, to my horror, use Zoom. Others have adopted a software suite to manage their entire practice. These therapists rely on the same company for scheduling appointment reminders, recording session notes, billing insurance, and running a video chat. When I have requested to connect via Signal, they express a preference for their platform, usually citing HIPAA compliance. One recommended a finding a provider who uses paper records as the only avenue open to me. But wasn’t there a time before companies like Spruce, SimplePractice, and TheraNest, where sensitive session notes were somehow distinct, less “networked” than today? How are therapists determining the privacy and security protections of their platform? How do I? Does anyone have experience with these companies?

First, some context. The latest from the US justice department saying that they will be focusing on finding "ANTIFA leaders" is incredibly troubling for anyone involved in leftist groups. I foresee a lot of good activists, regardless of how far left they actually are, arrested on trumped up charges in order to squash opposition.

Organizing is essential to resist fascism. This is made more difficult by the pandemic, as in person meetings bring a huge, almost unacceptable risk. As such, many orgs have been turning to platforms like Slack instead. Trouble is, Slack logs are not encrypted and I am certain that as a business based in the US Slack will not put up a fight to keep user data safe if the feds come calling.

I'd like to collect a decent list of alternatives. Important factors include encryption, ownership, open source status, ease of use, federation, scalability, hosting, cross platform, and anything else you can think of.
