If a disenchanted follower X reels off a list of things they don't like about blogger Y, like chewing food before starting an insta story, they've 'changed', they're flaunting their wealth, or any other arbitrary reason that only seems to affect only disenchanted follower X, then sure 'don't like, don't read' is a perfectly valid response as there's an obvious mismatch between blogger and follower.
However, if it's concerned follower X asking questions, about say transparency, or gifted items not being presented as such, the promotion of 'contraception' devices as viable alternatives to ones a GP would prescribe, questionable diet advice, etc. which have the potential affect more than just concerned follower X, as in the entire following and well beyond that, then 'don't like, don't read' just doesn't cut it.
The influencer currency is trust, a trust that is based on a discourse of honesty between influencers and influencees, if bloggers/influencers/whatever are seen to be abusing that trust they should be prepared to defend/clarify their positions, not silence the discussion, and certainly not utilise their following as foot soldiers whilst evading accountability.
