Honestly, the new licensing model for Oracle JDK was known for so, so long, and every company had every chance to use an open alternative. Actually I think Oracle has been pretty lenient with it’s grace period, so I don’t feel sorry for the companies held accountable over this
I think it’s more important than ever. Software is getting slower and slower, and the bloat is ridiculous. Imho this is because we just work with abstractions over abstracions ignorant to how it will be computed on a real machine. I think a more appropriate methapor would be, that you can speak and understand language (program) while being illiterate at the same time (not having a fundamental understanding on how a computer works). Of course this is a exaggeration, you don’t need to know about these stuff to be a adequate programmer I think.
