Why is it sad? I think that its refreshing to see a woman be fearless in expressing her femininity / sexuality AND her interest / expertise in tech. They're not mutually exclusive. A woman saying "check out my body, I'm sexy" shouldn't disqualify the "btw I make things." The tone of your comment is along the lines of "she was asking for it" :\
There's nothing fearless or feminine about implants.
The "camera review" videos on her channel where she walks around with selfie stick pointing at her boobs. That's just poor taste click bait, not "expressing femininity". View count jumps above 1 million the less she wears, but at what cost?
I've no idea about the main story of apology, I just found this today and commenting on her channel and choice of brand promotion. This to me would easily cause lack of trust with whatever she does, simply because of her willingness to self-exploit for view count.
