Re: Slack should ..
I’ve seen this a few times. One was a large UK company storing data for a government body. When it came to transferring the data away, their reply was ‘no, we own the data’.
There was another incident reported by The Register a while ago. The company went insolvent, and customers were told to pay £xxxxx now or lose the data on the servers rented to you.
Sadly, it’s not confined to software and servers. We received a notification from TalkTalk a couple of years ago stating that our leased line would be changed mid-contract from a fixed-fee to whatever they decided to charge. They gave customers 30 calendar days to quit their contract, or be tied into the new contract for the remainder of the agreement, knowing full well that it’s almost impossible to get a leased line installed from anywhere else in that time. Their charges have increased by around 50% since.
