Solar flares are predictable, with a decent lead time, so they could ground them during solar activity. But when the cost is potentially so high, an abundance of caution does make sense.
Would be good if the articles had linked to an official statement.

You have to dig reasonably hard, but a few articles have linked to the original EASA directive, which is allowing up to three non-passenger flights to relocate the plane to a service location.
I'm not sure if that rule would just apply in Europe where they have authority.
