It's near impossible to work as a professional academic without learning English well enough to publish in it. Furthermore, in many fields you need to move countries during your academic journey and learn a language. For example my previous PI was Spanish (Catalonian actually) but did his PhD in Paris, so he needed to learn three languages in addition to his native tongue. Other lab members were French, Italian and German, all again having to have learnt English so they could each communicate with each other but also publish. The international collaboration is already there, and it's aided, not hindered, by the use of English as a common tongue. It's a two way street as well, if an academic can't read English than they effectively cut themselves off from 95% of the research in their field, and most certainly the most impactful research. Lastly, most journals offer paid translation services and a lot of Universities will similarly offer a service, so it's almost a moot point.
