Subject: Your company ExampleCo will soon manage your Trello account
Good news! Your Trello account is getting an upgrade.
ExampleCo will now manage Trello accounts with a example.com email address,
which includes yours (mjd+trello@example.com).
The "Good news" part looked like marketing bullshit, but the rest of the message was menacing enough that I was able to contact them by email and get instructions about how to avoid having my personal Trello handed over to ExampleCo.It still sucks.
The lesson I take from this is: “Software as a service” is always a security risk. Unless my data is on my server, someone else owns it and might sell it to a higher bidder.
This is one of those “fool me twice, shame on me” moments.
