As others have mentioned this is mostly marketing and not UBI for many reasons but one thing that irks me particularly with this initiative is selecting candidates based on occupation. The *whole point* is to *not* select based on who is more or less deserving, that exists already and is called welfare.
At best, this is a way to waste some political capital of UBI supporters, and at worst, will be used to push UBI back another decade in Ireland. For this reason I think any communists and socialists who support UBI should refuse to acknowledge this as UBI, and use the vulgarism "welfare" instead exactly as you suggest.
