For example, I'd been using Wunderlist for a long time and was a very happy user. They don't charge money, but I would have gladly paid whatever they asked. Then one day I woke up and found all my tasks were gone! Well that's what I thought at first. I soon realized they weren't gone, they had just all been removed from their respective categorized lists. I filed a ticket [1], and then emailed them when I received no response.
After several back-and-forth exchanges with their support, the answer I received was, sorry, we cannot restore your lists to any previous state and we don't know why it happened, all you can do is manually move them all back to their lists. All 1022 tasks. By hand. With no explanation or guarantee that it won't just randomly happen again at any point in time. And then they tack on their "apologies for the trouble". Absolutely astounding.
Not to mention, their response that they "can't move tasks from one list to another", or that it's not possible for them to restore my data to a previous state, is either a lie and a complacency, or it's extremely concerning in that they don't apparently have backups of data.
So yeah, my point is, when large companies do it, I somewhat expect it as part of their economies of scale; at least it's not personal (which could be a good and bad thing). When a small company does it, it feels almost like a betrayal.
EDIT: Got so caught up I forgot to mention my actual point.
