The first reason behind this "reform" is to steal and sell Academy's real property, the only Soviet legacy which has not been stolen until now. The scheme is traditional to Putins' friends:
1. Pour state money into property, paying for its repair, landscape development and luxury buildings. All paid by simple Russian citizens.
2. Name the property as "unuseful" and sell it to the pocket company for a laughable sum.
3. Resell the property for its market value. Share millions of $$$ between government officials, who let that happen.
The second reason is political. The Academy and scientific society in Russia was a pain in the ass for Putin, with his neo-religious policy and his fraudulent friends. Several dozens (!) of government officials have been caught with fake scientific works full of plagiarism. The "miraculous" water filters, which were going to be forced by one of Putin's friends in power to be installed in every Russian city, were shown to be a hoax. There were many, many other collisions between scientific society and our fraudulent government. But it is over now.
Stay tuned for new "scientific" discoveries, about how Holy Water heals cancer and a prayer lessens rocket failure rate. Assuming we will still have rockets.
