On a general basis, both as an organisation and as individuals, we tend to keep nagging hardware vendors permanently. Indeed it appears that the Brave GNU World was dropped from the UK Linux-Magazine also because readers complained that I was nagging too much -- at least that is what the comments of the editor seemed to imply.
Negative comments tend to cloud the positive ones, so here is a postive one: I want Brave GNU World back!!! It was one of the few things I enjoy reading, and have been wondering what the heck happened to it.
So I'm not sure that more nagging will help, rather than have the opposite effect of alienating people to our valid points.
Random nagging no, but if it is directed, it will help. Also, we shouldn't be bothered if it alienates people, we are fighting for freedom, such fights will always alienate those who wish to destroy what we work for.
