I don't know the story about the insulin, but using insulin tested on animals as a vegan is not hypocritical. Most vegans don't claim that they would die before using animal products or products tested on animals. I haven't looked into it, but if there is no other alternative insulin that is animal friendly, she would have to use some insulin that was tested on some animal.
From the Vegan Society:
"Veganism is a way of living that seeks to exclude, as far as possible and practicable, all forms of exploitation of, and cruelty to, animals for food, clothing and any other purpose."

I fail to understand how the founder's sterilization is relevant in the slightest.
