Possibly, but that sounds like a problem which could be solved separately, perhaps with stricter laws about what constitutes an onerous contract; we need not discount UBI entirely because it causes some problems, since the problems UBI causes might be better than the problems we have without UBI, and the problems with UBI might be easier to solve.
If the issue of predator treatment of consumers were addressed first, a large amount of the pressure for UBI will evaporate. The poor are poor due to predator capitalism, not due to any lack of skills on their behalf.
It might be that UBI is politically potentially possible, while the other issues are not politically viable to solve in the present situation. Politics is the art of the possible.
