is it really FOSS?

OpenProject

Project management software

Yes!
This project appears to be free and open source software.

Details

The project is provided under a GPLv3 license. They do offer an “Enterprise” version of the software which enables various extra add-ons, which are accessed by purchasing and activating an enterprise license, but these also appear to be part of the GPLv3 codebase as confirmed in their FAQ and from users finding workarounds.

The project is a fork of ChiliProject (GPLv2), which was a fork of Redmine (GPLv2+).

Despite being a fork of GPL-based works, they do require contributors to sign a CLA which hands over relicensing rights which may indicate potential future plans.

The project appears to gain revenue from selling its enterprise licenses, providing hosted versions of its software, and from providing support services.
