I can address some of your questions as I have already done in different occasions on SF.

Regarding the beard
This is one of the Islamic traditions being wiped out from the land since 1924. From this date on, not only beard but also face-veil, jubbah, imamah were wiped out from the brains and minds of people. Muslims undergone severe mass-conditioning regarding all of these issues. By the fall of Khilafah and during the re-construction of modern Turkey, new heinous laws were established so to ban dress style and outlook of the people. Many many thousands of people were shot to death, hung or brutally killed just for not following those orders. Not only that, but reading Adhan out loud in Arabic was strictly prohibited. Layman and the scholars are subjected to severe trials and tribulations...

Later on Adhan was restored to its original proper Arabic, however, beard till this day was banned in official places, such as military service, yet military service made obligatory. There was no choice other than two: either grow beard till one goes to military service, then be subjected to humiliation and indignity by being forced to shave it.

These all are started by by first ruling party, but then continued severely by godless mafia called "Ergenekon". These are the enemies of Allah who are mostly come from non-Turkish origin. They overthrew ruling government whenever they saw some sort of "Islamization". During these overthrowing scholars with beard, scholars with Sunnah dress were hung for no reason. Beard and all Islamic traditions were mocked and demonized publicly, even in schools... They invented a method to "control" religion and the practice of Muslims, by introducing official government dependent religious affairs authority called "Diyanet". In almost all mosques throughout Turkey, same Khutbas are preached. These khutbas are prepared by appointed scholars in Diyanet. Imams, are government employees that are being paid by government. Instead of Madrasah, these Imams are mostly University graduates from faculty called "Ilahiyat" where they get to learn modern Arabic, fiqh, tafsir etc within 4 years.

Having seen these brutal torments, the scholars of late Ottoman and modern Turkey, adopted the Shafi'i ruling regarding the beard - that's being Sunnah. Not only that, but also ongoing severe situation is considered as "Karahah" under which certain things can be allowed. Till this day, they continue this adoption because the ban is still there, perhaps this will continue until those barbaric bans are totally lifted.

As you see there is sad history behind all of these that needs to be studied well in order to understand state of our fellow Muslim Turkish brothers.

Regarding the weird behavior of Muazzin
It is not a big deal. They do it to recite some Dua after prayer with a microphone which is located just there. So, if you provide them with a wireless lapel mic, then I think they might join in the first raw.
