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.

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.

Someone pings you in slack or github (or discord or on a forum post or wherever) asking for something. Perhaps some advice or a code review. After you help them out, they say "Thanks!". In normal conversation, I would respond with a "You're welcome" or "no problem" or something.

The problem I have is that while I want to be polite and acknowledge their thank you message, I don't want to generate notifications or otherwise distract people. Responding with a github comment will notify and probably email any involved persons. Slack and discord it depends on the channel, but many channels have low enough traffic that I will check every time theres a new message in that channel (and I'm sure I'm not the only one monitoring those channels).

Its not really a big deal and no one is going to get angry about it - but it can distract people or ruin their flow while working and I want to avoid that. In my mind, a reaction emoji is perfect for this. It acknowledges the comment or message if someone looks, but doesn't send notifications or light up the channel name.

...but which reaction should I use? I've never seen a "you're welcome" emoji. I've been typically using a thumbs up (:+1:), but that can look as if someone is seconding the thanks rather than me trying to acknowledge it.

Is there a better way to say "you're welcome" or "no problem" in this situation? Is there a better reaction emoji on github/slack/discord/your communication platform of choice? Should I stop worrying about possibly savings other people an email or small distraction and just say "np" or something?
