No, it’s not. Lego has been bullying local distributors of other brick systems (e. g. CADA) by issuing patent claims, knowing very very well that those claims are false and the patents have expired long ago.

However, customs has to hold and store the shipping containers until the court settles, and they charge for it. A lot. This forces small shops (down to your local mom&pop toy store) to pay for customs storage fees, for weeks, sometimes months. These costs are high enough to force small shops out of business, mind you.

Along with the declining quality of the sets and the increasing cost, Lego is very well a shitty company.
