Nobody is agitating for 'string' to be replaced with 'character sequence'. It would be more descriptive, more literal, easier to understand than 'string' which usually means something completely different and not obviously related to character sequences at all. But nobody submitting passive aggressive drive-by PRs to public repos demanding that the word 'string' be stricken because isn't literal or self describing. Because nobody really cares about words being literal and self describing, that's a transparent post-hoc justification for what is fundamentally political activism.
