Elsevier are disliked for litigation against scihub+libgen, IIRC? Also might be noteworthy that they have a long controversies section on their wikipedia page (including lots of things I'd never read about until now) while Springer and IEEE have none listed.

I couldn't find ACM, what does it stand for?

Association for Computing Machinery. Theoretically everyone in the computer science field is not just aware of them but is a member :)

Yes. I work in CS in the field of Computer Graphics and (by association) Computer Vision and Robotics. Our top conferences and journals are by ACM. However there are a few journals by Elsevier and IEEE which are relevant. I do not have (legal) access to any of those three. However there are publishers who allow authors private/institutional hosting of their papers without paying additional open access fees. I would still doubt their legitimacy in tax funded research results...
