I have seen sheikh assim many times conflate his personal views, which aren't based on Quran/hadith, with the fatwas he gives. This and some other fatwas of his essentially say something is haram or makruh, and then in lieu of a reasoning, just say why would you want to do it anyways.
On the other hand this is the same guy who says meat in Europe and the US is halal unless proven otherwise because "christian country", without ever mentioning the different slaughtering practices. So it's not like he generally errs on the side of strictness. If anything, he usually leans on the side of permissiveness.
