I have, as a user, when I was living a previous life at different big banks (where I either scheduled deployments and downtimes, requested access to some restricted systems or created IT support tickets through Snow). I hated it more than Jira - it wasn't slow, just confusing, random, cryptic, and non-sensical.

And looking at the screenshots from the article, it looked nothing like that. Like a totally different application. I guess the banks have over customized it? (Though interestingly the Snow instances looked very similar to each other at all places where I used it)
