Every now and then, I come across download archives in this .RAR format.
The formats have different versions: v4 and lower can be extracted with
Free Software tools like unar <https://theunarchiver.com/command-line>,
while v5 needs a non-Free tool.

A few times now, when I come across a v5 RAR archive, I try recompressing

I have to admit that I'm not a fan of the .RAR format, but only
because I never have a tool on hand to decompress the pirated content
I found compressed in the .RAR format. Every time I want to find ROMs
for a variety of old video game consoles, whoever compiled the
collection always insists on .RAR rather than the more convenient
.ZIP.

I will agree with you though. The fact that more recent .RAR files
can't be uncompressed without a proprietary tool is alarming. I
imagine that something similar will happen to office formats in the
future: files created today won't be readable by the new software or
vice versa. This is partly why I always wanted my documents to be
saved in the OpenDocument standard. It's too bd that my workplace, a
public school which would benefit from using open formats that are
free of charge to use, insists on the Office Open XML stuff.

I never understood why .RAR was common..
.zip is good for compatibility
.7z is really really good
.tar(.gz) is good for linux compatibility and to just tie a bunch of
files into one without compression

At least in my opinion.
