The worst ones are the ones that add a whole paragraph to their spam to explain why it isn't spam and they have a right to send you their junk.

Yeah, those are lousy.

Even worse though are places like Atlassian, which add a footer to some of their emails like "this email can't be unsubscribed from".

Even though it's directly illegal for them to have emails that can't be unsubscribed from.

It's their own special "Fuck You!" message to their email recipients.

Their lawyers will argue that’s a transactional email part of the functionality of the app, so they can play fast and loose with legal requirements

I'm not even their customer (and never will be), so not really sure what kind of app functionality they'd be claiming. :/

But the concept of your comment "they're just doing what they want because they reckon they can get away with it" is pretty common among large tech companies.
