That was very nicely worded.Every FTP client on the planet defaults to binary when there is no extension except Filezilla.

If the file format is unknown, leave the file unchanged and transfer it 1:1. Anything else is [self-censorship].
There are other default settings that can cause transfer problems for some users, as we have discovered during several support cases. We have a dedicated article for this. Here is the relevant part translated:
The following are the necessary settings changes:
- Edit > Settings > Transfers > Limit for concurrent downloads: 1
- Edit > Settings > Transfers > Limit for concurrent uploads: 1
- Edit > Settings > Transfers > FTP: FIle types > Default transfer type: Binary
- Some files can be transferred empty (0 bytes).
- Some files aren't transferred at all.
