Body of the toot:
Absolutely unbelievable but here we are. #Slack by default using messages, files etc for building and training #LLM models, enabled by default and opting out requires a manual email from the workspace owner.

What a time to be alive in IT. 🤦♂️

“Data will not leak across workspaces because trust us.”
Yeah, and every other LLM has demonstrated such great abilities to avoid reproducing training material 🙄
I have no idea how they feel like they can back up like half of these claims. Not that it matters, if something leaks they’ll just say “oops, nobody could have seen this coming” and then move on.
I, for one, welcome our all-almost-knowing trade-secret-leaking waste-of-time-and-resources LLM overlords
What does this mean regarding their claims that data is encrypted at rest and in transit? https://slack.com/resources/why-use-slack/slacks-enterprise-security-features
- ‘at rest’ → we’re using filesystem encryption
- ‘in transit’ → we’re using TLS
neither is end-to-end encryption, the data is not private to the service provider.
That’s just a fancy way of saying they use tls, like the rest of the world.
They decrypt it once it hits their servers and do whatever they want with it.
ah ok, so if it’s not at rest and it’s not in transit, what else is it?
vibing
In their database lol. I’m sure whatever file storage they use is encrypted but doesn’t matter when you have the keys and can view all the data unencrypted.
is it that easy to sell this shit to the average CTO?
Unfortunately corporate security is a joke in many aspects.
there is a type of leader out there that takes gartner magic quadrants seriously and makes decisions from that information
and they’re not rare.
I’ve done UX on a few B2B SaaS things and the U meant CTO in most (sanctioned) cases
As long as you can check the boxes to an auditor.
you see, your data can never be at rest if they’re constantly using it to train LLM models and exploiting it for other marketing purposes
…god this is stupid enough that I’m very sure I’m going to hear it in earnest from some AI shithead next time one of our threads hits all
at rest, in transit, in plunder
…in perpetual motion
they use it for their matrix screensavers
out jogging: that’s you keep data fit. gotta keep it moving. unfit data quickly starts falling into bitrot. that’s what you get by buying a slack subscription - crosstrainers for your data!
trade secret tho, don’t tell anyone
Has anyone used Mattermost? Has anyone switched to Mattermost? How’s hosted Mattermost?
It passes the tickboxes of “actually open source” and “you can just buy hosting”, but I don’t know how it goes corporateishly
@dgerard @rinze We have self hosted it for a few years. Small scale, but we did move a couple of GB of data archived from slack into it. I’ve found it pretty solid and like having focalboard built in.
Real deletes are an enterprise feature, but I have a nasty little script to remove “deleted” attached files.
(tried it some many years ago, probably long enough that lots of the following is entirely outdated)
then: install was relatively clean, UI shit still had a lot of work required (not showstoppers, just lots of not-quite-good things as often found in oss stuff), wasn’t great to monitor/profile, client options were narrow, and lastly the standard problem of being non-goldenpath-choice meant you had to do a lot of things yourself
it was an internal-only service in a always-use-vpns-for-everything company so further attempts at SSO and integration and ACL shit weren’t investigated at the time

if we got it it’d be the corp offering - if the data could be exported to an open source instance.

My chair at TUM uses Mattermost for most internal communication. I’m aware of a couple different academic institutions that do that.
EDIT: Perhaps of important note, we’re talking Computer Science systems people. Like, kind of an environment where you’re professionally obligated to have strong opinions about Linux distributions.
In all cases it’s self-hosted. I don’t know anyone who bough hosting. If I get my hands on our sysadmin I could share more.
As for “switched” - I was at one company only that had an official/unofficial Slack and we were given stern talkings to about never ever sharing any company information through it. It was specifically for watercooler banter. Basically “treat it as a personal non-work environment”. Specifically because our security officer was aware that Slack is not end-to-end encrypted and that’s just an immediate dealbreaker in any sane company that handles sensitive data. God I miss that CSO, I didn’t know how good I had it.
Microsoft has Yammer because they always need to choose the worst possible tool in existence.
The company I work at uses selfhosted Mattermost. Granted, we’re <50 Employees, so I don’t know how well it scales for larger companies.
