Atlassian, what happened?

I’ve always heard and seen Atlassian and others like Canva as the poster child tech companies to come out of Australia, and had noticed them having extremely positive reputations and feedback on sites like glass door for example.

Recently however, I’ve noticed Atlassian has dropped to 3.7/5 after being well above 4, and seemingly relentless negative reviews coming in.

What gives? I see a lot of comments about Amazon culture leaking in, things like stack ranking etc. Has it really gotten that bad?
