Is there any reason Watchtower is disposing of their Islam-focussed literature and replacing it with a generic brochure?
Yes, they mentioned it in a letter a few years ago. They said Muslims are more likely to outright reject anything that seems critical of Islam, so it's better to witness subtly.
Hmmm. A repressive, high control religion that forbids its' members from reading anything that's critical about it. Sound familiar?
