In this this question, Federico Poloni's wrote an answer:
You can write an e-mail to the authors and ask for a copy of their published paper. Almost everyone will be happy to send you one. [...]
which is a very good answer. However, as an academic, I wanted to share my experience on when I would use the suggested solution. I added a comment in line with:
I would only write to the authors if Sci-Hub dies.
This is not only my choice. For too many fellow academics and scientists, Sci-Hub is the first option, even when legal access exists.
Unfortunately, my comment was deleted. It was by no way unconstructive, offensive, or rude.
Would the moderators kindly justify the deletion? Wasn't it opinion-based?
