Its not because it is conditional -- both means-tested and conditioned on meeting specific other participation requirements (which are, apparently, both age-dependent and in many cases time-limited after which the participation requirements change.)
Its a pretty standard example of the kinds of conditional welfare programs in opposition to which UBI is offered.
UBI is neither:
1) means-tested: because this creates perverse incentives against work (reduces the marginal value of outside income) and increases administrative costs (because you need to take information on means, verify it, and determine benefits based on it, all of which changes over time.), nor
2) conditioned on participation requirements (for much the same administrative reasons as apply to means-testing).
