Vanilla OS
5 تارن مان 4.0 (1 جائزو جي بنياد تي)
Vanilla OS is an immutable and atomic Ubuntu Linux-based Point Release distribution, that receives updates at the right time, neither before nor after, without sacrificing security and functionality.
VanilaaOS is a trade-free operating system, the only drawback might be the search engine that is used by default in the browser: Duckduckgo. While it is true that Duckduckgo does not collect personal information, the official business model is advertising (https://en.wikipedia.org/wiki/DuckDuckGo). Therefore, 1 block could be subtracted and 4/5 blocks could be given.
