If you can recall back to around 2010 or thereabouts, there were rumours of US telecom provider Verizon entering the Canadian market. The big three Canadian pieces of shit spent MILLIONS on advertisements crying about facetious bullshit that pretty much nobody believed. Verizon ended up noping out anyway, presumably because of how shit our infrastructure is.
They could have spent that money to improve their service and be companies people actually want to deal with... But nah.
It's been a while since I've been in that situation, but I used to just make a common folder /steam and create a group with access to it. I'd then grant all users access to that group. Seemed to work fine?
