Give it a break. That article is 2.6 years old. Some of the points might still be valid, but there is a solution (and probably was at the time of writing as well) to every and each of the problem mentioned there.

Regarding the quality of reusable apps, well, it's like with all other software libraries out there.

Nothing new.
