They probably just used now-outdated practices before those practices were outdated. This happened in the past, remember. Sure, the cloud is a thing today, but was the cloud such a thing 5, 10, 20 years ago? Do you really think it's their fault for not knowing in advance how much of a thing the cloud would one day become? Oh, how outdated. Sheesh.
Yes, yes, and no.
For example, https://www.explainxkcd.com/wiki/index.php/908:_The_Cloud is from 2011.
Old animation though I wouldn't necessarily expect to only have been 10 years ago, and 10 years ago I wouldn't expect to be scolded for not using the cloud.
Clouds have user accounts too. I have seen dead links to documents in a former employees space on sharepoint, confluence, and google docs.
Who knows what happens when I've shuffled away from my current company.
Dead links are also incredibly common, particularly because we are on our nth port from sharepoint to confluence to whatever back to sharepoint. Generally, because C levels don't want to pay for this year's price hike.
I see this scenario play out constantly:
1. A team or staff member has a project's data located on their user account or hardware.
2. The team or staff member are made redundant when there is a dip in earnings.
3. IT make a backup of the user account/s and wipe the hardware, and because it's older usually move it on.
4. Months or years later that data is needed and at this point no one at the company actually knows where the data is - and even if they find something, they don't know if that's the latest or the full version.
Now this wouldn't be a problem if there was a decent overlap in staff retention, but that simply isn't the case these days.
Writing better storage policies doesn't help - it's the understaffed nature of their businesses which mean that there is no time for staff to keep up with basic data housekeeping.
The types of data that clients should have on hand, but nevertheless have asked me to supply, are frankly embarrassing.
