For clarification, FileZilla itself does not appear contain adware nor has it switched to ads within the app from my analysis. The main download page for Windows installers contains a bundleware offer within the installer as you install (this offer may currently be offline). The installer filename contains the string _sponsored_. If you click through to the show additional download options, you can get all the installers without bundleware for all OSes.
