"May have " and so much "simply".

I didn't read the new biography ""Charlotte Bronte"" from Claire Harman. Off course not, because it is only two days ago it is published. But I am a little surprised by the reactions I am reading. For instance this one:

From: Charlotte Brontë: A Life by Claire Harmann review – a well-balanced, unshowy biography
theguardian

In the pragmatic 1990s, Juliet Barker worked hard to clear away the consequences of Gaskell’s well-meaning gothicisation by rebuilding the Brontës’ story on solid historical grounds. In particular Barker challenged her portrayal of Patrick Brontë as a storybook ogre. Charlotte too was transformed from a sequestered tragic heroine into a chippy spinster who carefully stage-managed her rise to literary fame by persistently pushing herself and her work, even the duff stuff, before the public.

As a highly experienced biographer, Harman has too much integrity to suggest that this idea of her subject as a proto-modernist is entirely fresh. Nor does she even hint that she has uncovered any new documentary sources about her. Instead, she wisely concentrates on rounding out and deepening aspects of the author’s life that have been previously scanted or skewed. Particularly fine is Harman’s reading of how the tortuous, sexless love affair between Héger and Brontë could ever have been allowed to reach such heights – or depths. Previous biographers have tended either to castigate Héger as a married flirt who led Brontë on, or they have painted her as a disordered spinster, randy with celibacy, quite capable of spitefully destroying a man who refused to make love to her. (...)

Harman, by contrast, suggests that what we may be looking at is primarily a cultural misunderstanding. Héger routinely lavished his pupils with a repertoire of kisses, pats and affectionate glances. Brontë, raised with brisk Yorkshire non-showiness, may simply have misread pseudo-parental tenderness as a special favour. What’s more Mme Héger, far from being as sly and vengeful as her fictional avatar Mme Beck, was simply a sensible businesswoman who realised the damage to her school’s reputation if gossip emerged about a tendresse between her husband and the plain, nervy English governess. Deciding not to respond to the stream of yearning, abasing letters that Brontë wrote once she had returned to Haworth wasn’t a vicious move on the Hegers’ part, but simply self-preservation.

I am an admirer of the biography of Juliet Barker and I really don't recognize that I ever thought:

Is everything really that "simply"?
