Make no mistake: Lego makes a great product but they are an evil corporation. They have been so from the day they started making bricks (they stole the design, the marketing content and even the boxes), they continued when they sued everybody and their dog for doing the same thing that they themselves did, only much worse, and finally they did it again when they acquired Bricklink and started merging accounts with the Lego website. And probably many times in between when they created incompatibilities between older and newer sets just to drive sales.

Lego... incompatibilities?

Isn't compatibility a huge part of the draw of Lego?

I've never heard of incompatibilities, what are they?

The only problem I've noticed product wise is there are now mold defects after they started adding recycled plastic, only one or two minor (visual surface) imperfections per box, but before, there were none.
