The issue here is not bad English in the sense you'd expect from a learner or someone who just isn't fluent. Nobody minds that, although you say not everyone can afford professional editing services: that's what journals are theoretically for! The actual problem here is fluent English that is written in a totally bizarre style only found in academic papers. I've found that academic-ese is less of a problem in good computer science papers (like the one this article is about), but it crops up in some fields a lot. A trivial and not very important example is the way minor things are routinely described as "novel", a word you rarely find in everyday English, but in the research literature everything is "novel".
