Cecil Sharp is also respected[ he has a house named after him, however his judgement of songs was coloured by the time he lived in, he bowdlerised songs, which had sexual connotations[ although he kept the originals]

All these collectors including the Broadwoods had a vested interest in popularising the songs for the piano, cleaning them up AND REMOVING SEXUAL CONTENT so they were acceptable for Victorian standards of prudery
