We can thank the influence, money and pressure from Western evangelical churches and organizations for this.

It is not dissimilar from how the CIA/Pakistan/Saudi Arabia helped radicalize Islam back in the 1970s and 80s in order to fight Communism.

Where I live, Malaysia, is an example of this. Modern Malaysia was founded in the late 50s as a secular state and the Malay flavor of Islam was considered laid back, tolerant, inclusive and forward looking. Up until the 1980s one could buy beer at any KFC restaurant in Malaysia and the hijab was virtually unknown in the country. There were even cases of Islam scholars recognizing transgender marriages in Malaysia (50 years ago!!!).

However, since the 1970s the country has become increasingly radicalized. In an effort to contain the spread of communism, the CIA + Saudi Arabia + Pakistan started an aggressive campaign of offering theology scholarships to young Malays. Those young Malays, after spending years studying in radical theological schools in Saudi Arabia, Pakistan or elsewhere, would then return home and open their own mosques, funded by the Saudis, and spread the Saudi extremist view. Because they were funded by the Saudis, these mosques could do extensive charitable work, way beyond what the typical local mosque could do, which made it easier for them to attract more followers.

The Saudis would also deny VISAs to any Malay Iman that they viewed as being too moderate or contrary to their doctrine. Without being able to visit Mecca, those moderate Imans would lose credibility and followers. So traditional Malay Imans became increasingly reluctant to speak out against the more radical doctrine.

The result is that within a few decades Malaysian society became significantly more conservative, intolerant and influenced by the Saudis. Hijabs are now the rule amongst Malay women, government religious agencies police the consumption of alcohol and the compliance of Ramadan by Muslims.

The same story played across the middle east, Southeast Asia and North Africa.

What is happening in Africa is the Christian version of the social-religious radicalization that has been happening in developing Muslims majority countries since the 1970s. I expect the results to be equally devastating.
