You don't have to buy anything to open rar files. 7zip, winzip, winrar,
and probably a dozen others can all open rar files for free.
Providing a ghidra file WAS already the most considerate option since no
one has to buy anything. IDA is a commercial app, ghidra is open source.

when people use RAR files believing everybody has a paid WinRAR
subscription when there are other archive formats that are open and I
thought I was just dealing with yet another archive format.
