Looking at this from the security point of view, a complete de-branding / re-branding is essential.
Do a Google search for "FrontAccounting 2.4.4 - Login" and it will ferret out all the native FA code based installs. Do that for older (known vulnerable) versions and it might be a security nightmare.
Even if you do what you want to do, make sure there is a flag in the Company Preferences (sys_prefs table) to turn them off without having to wade through the code base. If most will then hide it, the exercise would prove useless.
Popularising FA is best done by word of mouth and through articles / reviews / courses across nations in all languages.
To be truly effective, the Chart of Accounts and Language extensions should be up-to-date and all schemas in synch. Transifex is where I hammer it out.
Also the FA pkg repo should be up-to-date so that the extensions will install correctly and work as desired. In fact, the extension packages were signed for that very purpose. For now, users are left to manually install from the FA24extensions repo.
