I don't think moving the log files is a smart choice.
All the tutorials and instructions would have to be changed and I don't see a valid reason to move them other than "I would like them to be somewhere else"

IMO, it's not a preference but a standard in any application to collect also log files in a folder (not mixing them with unrelated files such as binaries, dll etc.). Folders are already used for all other stuffs such as config, captures, patches, screenshot etc. so just asked to make the code consistent doing the same for logs.
It is controversial to belittle the most important stuff for troubleshooting (logs are mandatory for any bug report) not giving to it a proper location (highlighting its importance) preferring to mix it with something different with the risk also to cut&paste (e.g. when you have to collect them for a bug report) wrong files (e.g. binaries).
Users could simply open (e.g. with file explorer) the log folder and zip/drag&drop the entire folder or the specific files (RPCS3.zip, RPCS3.log etc.). It is more readable, with no risk and no need to filter out unrelated stuff.
Updating a tutorial is not a problem. Also, if you see a folder named log everyone understands, more than it is now, that log files are there).
