And? For any coding project to be successful, it has to accept new coders periodically. Behavior like Linus' behavior here drives those people away. This could easily be code written by somebody who was just starting in the project, a person who could have used some guidance as to best practices. The right thing to do is find out why the code review process failed to catch this problem.
Really, not following best coding practices is never a reason to verbally attack somebody.
The word "demand" is just bad headline writing. Blame Soulskill, not tech companies. This letter is more, "You should do this because it will benefit the US in the future in a way that is important to us as well."
As for local tax breaks, a move towards federally-funded primary education would do more far more for US students, as tech companies tend to be clustered. If we got away from the idea of locally-funded education, we could actually have a system where a student in NYC could have about as much chance of getting a good education as one in rural Pennsylvania.
I suppose it depends upon the journal, but this seems unlikely to me. From my experience in physics, authors sending papers to people who request them has long been standard practice. For the papers I published, the copyright agreements explicitly carved out this as a right I had as an author.
C++, especially C++14, provides a lot of the nice features of a language like Rust, but will interact well with all of your existing C code. Far, far more engineers understand C++ well, so having somebody else pick up the project will be much less of a burden.
The main drawback of C++ is that it can be a bit of a tricky language to use properly. There are some unfortunate caveats that require some level of expertise to write code that doesn't blow up once it goes beyond moderate complexity (I highly recommend Effective C++ as a good book to read on the subject).
