If so, is it legal to translate an article (and link to the original article) on another website?
Especially when it's this simple, "water is wet", "prefer postgresql over mongodb", "no you can't legally copy content without being authorised by the authors, even if translated".
Offering your own opinion on the law is fine, but IMHO answering someone else's question with opinion on the law is probably the wrong side of the line.
Disclaimers don't help, either, the regulation exists whether you acknowledge being outwith the licensing or not.
So the beginning of OP's question wouldn't pose a problem.
The second part (asking about the translation etc) could pose a problem, but it's phrased generally so it may or may not.
Legal advice would be applying the legal information to a very precise and specific scenario. For example, translation and republication permission is not always dependent on permission from the copyright holder if a fair use exception applies in the relevant jurisdiction, and even with permission there could be other obstacles to various forms of copyright reuse like a relevant patent from a different rights holder or a previously signed contract promising not to do this. And these details, as well as the risks of various different legal and illegal choices, may depend on the jurisdiction.
We don't really have enough information to know if exactly what OP wants to do is legal, beyond an imprecise answer of "not generally" which as mere legal information is typically fine for non-lawyers to say even where legal practice is restricted.

There has been a history of "legal advice" being applied too broadly in practice, so a great deal of caution should still be exercised - https://www.yalelawjournal.org/forum/the-overreach-of-limits...
