The website would've been fine if they hadn't added anything, yet they went out of their way to insult a small minority of their visitors using a <noscript> element, and took the time to write a weird rant about how you should really enable Javascript for some reason (I guess they only know frontend stuff and don't know how to run a backend server?).
To me, this degrades the website to the level of "personal blog of someone with a grudge" as much as websites that'll redirect you to a rant for leaving Javascript on. For a personal blog, that's just a weird quirk, but for a supposedly scientific, academic space to publish research, that's just bad vibes.
This is an irrelevant diversion, and materially untrue - "> What a lovely hat\nIs it made out of tin foil?" is absolutely hostile, and that fact is not contingent on the number of people who disable Javascript.
Childish stuff like this makes sense for personal blogs, but this unwarranted hostility immediately made me distrust this organisation.
