I have to use their web interface every time I submit a paper to an Elsevier journal. It's like sticking needles into my eyes. It's this bad: in 2019, they still use an image map for their main menu.
A particular pleasure is when they force me to compile my TeX into a PDF. Via a web interface.
Then when I submit they'll "proofread" and "format" my paper, failing to spot existing errors, introducing their own, and outputting an ugly mess, maybe with two columns to make it really unreadable.
And then there's the stuff the article talks about: the huge fees universities pay so that our own work can be "open-access".
I hate them. I hope they go bust. I hope their CEO becomes homeless.
