I would expect James Webb has the same issue, and similar ways of dealing with it. It's just that it never hits the press, since it's a normal part of operations. I'm not sure why Euclid's icing issue is getting some attention now, from the ESA article this was expected. Maybe it's just that it's slightly worse than anticipated, and they're changing their way of dealing with it?
