They should lay off 100% and go out of business. An entire generation of devs has suffered with Atlassian's broken, unscalable tooling. In my entire career I've never met someone who actually likes their products.
Believe it or not, about 15 years ago, Atlassian tools were far better than their competitors.
I remember using Jira in 2017 on a "legacy" project (as opposed to the "next generation project" as they call it). It was fine. I don't mind backend slowness - one second is no big deal in the grand scheme of things. I actually liked Jira (for its features and functionality).
The problem nowadays is that the slowness has been distributed across both the backend and frontend. It's not enough to wait one second for the backend to respond, you now also need to wait for a pile of shit Javascript to load, parse and execute, which has its own subsequent backend requests that themselves take a second to load.
And God forbid you accidentally click anywhere or need to copy text, as now everything is clickable and incurs the same slowness if you need to undo the accidental action.
