I think there is a strange psychological trait that I have, and others may as well, where I am much more forgiving breaking my own stuff than having someone else do it.
When you host Jira yourself, the monthly subscription pays for Software + Software updates. When Atlassian hosts it for you, you're paying for Software + Software Updates + Service (hosting). When you hosted yourself, a team gets blasted for not monitoring it or updating it correctly. When Atlassian fails to do it (and charges for it) then they get the heat.
All that to say, I don't think it's a weird phenomenon, it's just you're realizing that you're paying someone else for something that's not delivered on.
People are more forgiving torwards themselves and their own folks, I can understand that. I'm just thinking it's important to make decisions based on facts. Some self-hosters walk around with this "my own basement is safer than Amazon datacenters" attitude and that's just not true (in most cases, I guess :D).
No. The basic assumption is only, that if I pay somebody money for the service and to keep things running, then sudden data loss is unacceptable (and a multi week downtime even more so).
Some companies cannot operate effectively without atlassian products, so a fuckup of that scale might just have legal consequences depending on whom it hits.
