Does Tuya App, Fabriq, Microshare etc can be integrated using OpenHab?

My client uses Tuya app for indoor and outdoor cameras, light switch, dimmer light switch, Outlet Mini Plug, Outlet Socket, Fabriq for Multiroom Speakers, Microshare for Outdoor Camera, Lechange for Doorbell. Please let me know if it is cheaper and easier to integrate all these apps using OpenHab?

None of these technologies appear to have a binding developed for OH. Furthermore, OH has limited integration with cameras that do not support standard protocols.

There are python and node APIs for tuya that can be used with OH. I know that the python one is being used.
It doesn’t look like the Fabriq API has been hacked
The same goes for Microshare cameras and Lechange doorbell.
