What is the reason for the difference in fatwas between answers number 36277 and number 30414 regarding the same issue?

Scholars have differed regarding the permissibility of spending ill-gotten money on building mosques, holding two views: absolute prohibition, or permissibility when there is a need. In Fatwa No. 30414, the ruling was prohibition due to the absence of need, whereas in Fatwa No. 36277, it was ruled permissible to spend such money on mosque rent due to the existence of a need, while considering that building and renting are not equivalent.
