When I first saw the article I thought it was just a joke by sarcastic parent. But, well, it's not...
On the one hand, she bought this set so she has rights to do whatever she likes. And that icludes gluing the set.
And in the comments she wrote that they glued only few pieces, which were falling off constanly. So perhaps it's not as bad.
The kid is probably happy to be able to play with his Lego spaceship without the risk of toy falling apart.
Well, he is happy now, but I guess he will be a little frustrated after few years when he grows up and tries to build some MOCs...
