Do accents remain stable or not? What is the attitude towards Keat's poetry and dropping aitches /h/ according to these articles?

As we can see from these two articles, the use of language is very conservative in different spheres of life. In poetry or literature, for example, it is expected that writers adhere to expected norms. In the case of Keats, who wrote phonetically without aitches, he was seen to be uneducated, or certainly not intelligent enough to be able to distinguish between written English and the spoken cockney language. Furthermore, the second article demonstrates the changing of language as a fashion, although depending on the context in which it is used can quite often cause offence or lend itself to ridicule, such as dropping aitches in the House of Commons.
