It's partly empathy with the person who did the work and had it stolen, in a field where the main thing people work for is credit. Maths isn't well paid, and doesn't make things that millions of people directly use.

It's also systemic, it cuts off the supply of results, if there is no reward any more for getting a result, the pipeline of maths will stop. It is the snake eating itself, which has a bad impact for all of us.
