I was in Kerala at the time of Eachara Warrier's death and noticed that it was front page news for all Malayalam papers. In fact most of them also had editorial features and one newspaper had a full page obit.
He was not forgotten in Kerala.
Of course, none of the mainstream English press found any newsworthiness in the death of this Hero. In any case mainstream English print media in India is trash; and to give them a benefit of doubt in this case- it can be be argued that its readers at large would not have known about Eachara Warriers struggle.
