Teams is so weird, “ Number of org-wide teams allowed in a tenant” is limited to 25. So my company can only have 25 “general” teams. I think it would be neat to learn the rationale behind some of these settings.

Probably to protect people from their own ignorance. If you are participating in 25 teams, it's likely already too many, general or not. Having to navigate 25 teams that are full of stuff doesn't concern you sounds like an absolute nightmare. You'd burn out everyone in the organization with a setup like this.

And this is about organization wide teams, meaning those teams that people are automatically joined in, with up to 10000 members... So probably something you want to steer people away from.

This is most likely due to those names not being allowed for files or folders in the Windows file system. MS Teams channels create a matching folder in SharePoint where file attachments are stored.

I bet there is another vulnerability here, although they also seem to blacklist % and ..

most of those are the usual forbidden path and filename characters.

% is used to surround environment variables for interpretation, for example.

I would love to know who fabricated this myth and decided to just tell the story as if it were fact.

I was about to say "Which is essentially leaking the existence of something terrible inside. They should be embarrassed to say something like this in public. Like saying you can't have %s or $PS1. Why the hell not? What are you doing with this user-supplied input?" But maybe it's more about what everyone else might do with a channel name. Ie they might cut & paste it anywhere, and I guess windows users aren't expecte…

they're SharePoint limits, man. Teams is backed by SharePoint and it's not a secret, nor is it embarrassing.

Kind of a garbage article because coincidence or not they are similar widths.

It’s pretty irritating when files and folders on my Mac can’t be uploaded to Teams due to this limitation. It’s only forbidden for Windows users.

This is a classic joke, but settling on a common gauge was really difficult, it was not just copying some old Roman standard. There were even riots when different railways started to standardize because common rail gauge meant you can move through the town without engaging with the local economy, see Erie gauge war. Russia still has a wider gauge than Europe and Australia has 3 different ones.

The Romans did not use war chariots, since they are basically useless in combat. They only used chariots for sports in the hippodrome.
